Tikanga Whakamātautau Kaha Rauemi Oneone
He taahiraa nui te whakamātautau kaha o te oneone i roto i te whakamahere me te whakatinanatanga o ngā kaupapa rangahau hanga, ahuwhenua, me te hangarau whenua. He rauemi rerekē te oneone, he rerekē ngā āhuatanga miihini i runga i ngā āhuatanga taiao, te hanganga kohuke, me te hītori whenua. Nō reira, he mea nui te mārama ki te kaha o ngā rauemi oneone hei whakarite i te pumau me te haumaru o ngā hanganga i hangaia ki runga. Ka matapakihia e tēnei tuhinga ngā tikanga whakamātautau kaha o te oneone me ā rātou tono i roto i ngā mara rerekē.
1. Te Hiranga o te Whakamātautau Kaha o ngā Rauemi Oneone
I mua i te matapaki i ngā tikanga whakamātautau, he mea nui kia mārama he aha te hiranga o te whakamātautau kaha o te oneone:
1. Haumaru Hanganga: Me whai turanga pakari ngā hanganga whare, ngā rori, me ngā piriti. Me kaha te oneone ki te tautoko i te kawenga me te kore e totohu, e hinga rānei.
2. Te Pūmau o te Pari: I ngā wāhi pukepuke, maunga rānei, ka whakawhirinaki te pumau o te pari ki te kaha kutikuti o te oneone. Ka taea e te oneone ngoikore te whakararu i te whenua.
3. Te Whai Hua o te Hanganga: Mā te mōhio ki te kaha o te oneone ka taea te whakarite mahere whai hua mā te whiriwhiri i ngā tikanga me ngā rauemi e tika ana.
2. Tikanga Whakamātautau Kaha Rauemi Oneone
Kua whakawhanakehia ngā tikanga whakamātautau kaha oneone hei ine i ngā āhuatanga ā-pūkaha o te oneone. Anei ētahi o ngā tikanga matua e whakamahia whānuitia ana:
a. Whakamātautau Whakauru Paerewa (SPT)
Ko te whakamātautau urunga paerewa tētahi o ngā tikanga tino rongonui mō te aromatawai i te kaha o te oneone. Ko tēnei tukanga he patu i tētahi ngongo tauira ki roto i te oneone ki te hama. Ko te maha o ngā whiu e hiahiatia ana hei whakauru i te ngongo ki roto i te oneone ki tētahi hohonutanga kua tohua (30 cm te nuinga) ka whakamahia hei tohu i te kaha o te oneone. He māmā noa iho tēnei tukanga engari e whakarato ana i ngā mōhiohio nui mō te matotoru me te kaha o te oneone kirikiri.
b. Whakamātautau Kutikuti Tika
Ko te whakamātautau kaha kutikuti tika e whakamahia ana hei ine i te kaha kutikuti o te oneone, arā, te kaha o te oneone ki te ātete i ngā kaha e puta ai te nekehanga. I roto i tēnei whakamātautau, ka whakanohoia he tauira oneone ki roto i tētahi pouaka kutikuti, ā, ka whakamahia he kaha whakapae kia pakaru rā anō te oneone. Ka taea te whakamahi i ngā raraunga mai i tēnei whakamātautau hei whakatau i te piripono me te koki o te waku ā-roto o te oneone.
c. Whakamātautau Triaxial
He tikanga uaua ake te whakamātautau toru-axial engari he tino taipitopito ngā mōhiohio e pā ana ki ngā āhuatanga o te oneone. I roto i tēnei whakamātautau, ka whakanohoia he tauira oneone ki roto i tētahi pūtau toru-axial, ā, ka pēhia kia ōrite mai i ngā taha katoa (pēhanga taupoki). Kātahi ka tāpirihia he pēhanga anō ki te taha kia pakaru rawa te oneone. Ka taea te whakahaere i tēnei whakamātautau i raro i ngā āhuatanga rerenga wai rerekē hei whakatauira i ngā āhuatanga o te mara, pērā i te whakamātautau toru-axial whakakotahi-whakaheke (CD), te whakamātautau toru-axial kāore i whakakotahi-whakaheke (UU), me te whakamātautau toru-axial whakakotahi-kāore i whakakotahi (CU).
d. Whakamātautau Pehanga Korehere
Ko te whakamātautau pēhitanga kore here e whakamahia ana hei ine i te kaha o ngā oneone uku kāore i whakapūmau. Ka pēhia te tauira oneone porotaka ki te taha tuaka kia pakaru rā anō. Nā te mea kāore he pēhanga i roto i te taupoki, ka whakaratohia e tēnei whakamātautau he mōhiohio mō te kaha pēhitanga o te oneone i raro i ngā āhuatanga kāore i te mimiti.
e. Whakamātautau CBR (Ōwehenga Whēra o California)
Ko te whakamātautau CBR he tikanga e whakamahia ana hei aromatawai i te kaha o te oneone mō te hanga rori. I roto i tēnei whakamātautau, ka panaia he piston ki roto i te oneone i tētahi tere motuhake, ā, ka inehia te ātete o te oneone. Ka tatauhia te uara CBR hei ōwehenga o te ātete o te oneone ki te ātete o tētahi rauemi paerewa. Ko te uara CBR teitei e tohu ana i te kaha me te kaha pai o te kawe.
f. Whakamātautau Whakaurunga Kōne (CPT)
Ko te whakamātautau werohanga kōne he tikanga taputapu e whakamahi ana i te kōne hei aromatawai i te kaha o te oneone i roto i te wāhi. Ka werohia te kōne ki roto i te oneone, ā, ka tuhia te ātete i puta i te hohonutanga o te werohanga. Ka taea te whakamahi i ngā raraunga ka puta hei aromatawai i te āhua o te oneone me ōna āhuatanga miihini.
3. Te Whakamahinga o ngā Tikanga Whakamātautau
a. Hanganga ā-Iwi
I roto i te hangarau ā-iwi, ka whakamahia ngā hua whakamātautau oneone hei hoahoa i ngā turanga mō ngā whare, ngā rori, me ētahi atu hanganga. Hei tauira, ka whakamahia pinepine ngā whakamātautau SPT me te CPT hei aromatawai i te kiato me te kaha o ngā oneone onepu, ko ngā whakamātautau triaxial ia ka whakamahia mō ngā oneone uku he uaua ake te whanonga.
b. Ahuwhenua
I roto i te ahuwhenua, he mea nui te mārama ki te kaha ā-pūkaha o te oneone mō te whakahaere whenua, te whakamakuku, me te whakamahi i ngā taputapu taumaha. Ka taea e te oneone he iti te kaha pēhi te pāngia e te nui rawa o te pēhitanga, ka whakaiti i te urunga mai o te wai me te tipu o ngā pakiaka o te tipu.
c. Rangahau Hangarau Whenua
E whakamahia whānuitia ana ngā tikanga whakamātautau oneone i roto i ngā rangahau hangarau whenua hei tūhura i ngā āhuatanga uaua me ngā āhuatanga hihiri o ngā oneone. Kei roto i tēnei rangahau te tātari i te pumau o te pari, te urupare oneone ki ngā rū whenua, me ngā huringa o ngā āhuatanga oneone nā te huringa āhuarangi me ngā mahi a te tangata.
4. Whakamutunga
He mea nui te whakamātautau kaha o te oneone i roto i ngā momo mara, inā koa i roto i te hanganga, te ahuwhenua, me te rangahau whenua. Ko ngā tikanga e kōrerohia ana i roto i tēnei tuhinga, pērā i te Whakamātautau Whakauru Paerewa (SPT), te Whakamātautau Kaha Kutikuti Tika, te Whakamātautau Triaxial, te Whakamātautau Kōpeketanga Korehere, te Whakamātautau CBR, me te Whakamātautau Whakauru Konukō (CPT), e whakarato ana i ngā huarahi kanorau engari he mea nui hei mārama ki te kaha me ngā āhuatanga ā-pūkaha o te oneone.
Mā te whakahaere i ngā whakamātautau kaha o te oneone, ka taea e ngā miihini me ngā kaipūtaiao te hoahoa i ngā hanganga haumaru ake, te whakatū i ngā tikanga ahuwhenua tika, me te whakahaere rangahau matawhānui mō ngā hangarau whenua. Ko tēnei mōhiotanga ka āwhina i te hanga i tētahi taiao haumaru ake, pumau ake hoki.
Mā te mārama ake ki te kaha o te oneone, ka taea e tātou te whakaiti i te mōrearea o te pakaru o te hanganga, te whakapai ake i te whai huatanga o te hanganga, me te whakarite kia whakamahia te whenua i roto i te huarahi tino whai hua, tino pumau hoki.
