Yuav Ua Li Cas Ua Qhov Kev Ntsuas Qhov Ua Tau Zoo?
Sep 18, 2024
Txhawm rau ua qhov kev sim ua pob zeb, ua ntej siv lub pob zeb slump, tseem hu ua Abrams cone, thiab sau nws nrog koj cov pob zeb tshiab. Lub khob hliav qab yuav raug muab tshem tawm, thiab cov pob zeb yuav raug pom nyob rau hauv kev sib raug zoo npaum li cas nws 'slumps' yam tsis muaj hlau casing nyob ib ncig ntawm nws. Koj tuaj yeem soj ntsuam qhov tshwm sim thiab tseem ntsuas qhov ntau npaum li cas cov pob zeb tau poob los ntawm qhov muab lub khob hliav qab rau nws thiab ntsuas qhov sib txawv ntawm sab saum toj ntawm lub khob hliav qab thiab qhov siab ntawm cov pob zeb slumped.
Muaj plaub qhov txiaj ntsig ntawm qhov kev xeem poob qis:
| Qhov tshwm sim | Kev piav qhia |
|---|---|
| Zero poob | Yog tias cov duab tuav tag nrho thaum lub khob hliav tau tshem tawm, qhov sib tov qhuav dhau thiab tsis ua haujlwm. |
| Muaj tseeb poob | Qhov no yog qhov tshwm sim poob qis uas koj tab tom npaj rau, thiab txhais tau tias cov pob zeb yog qhov zoo sib xws. Qhov sib tov yuav khaws nws cov duab ntau thaum lub khob hliav qab tshem tawm, txuag rau me ntsis slumping los yog flattening rau saum. |
| Shear poob | Qhov sib tov yuav poob qis rau ib sab, thiab qhov no txhais tau tias nws ntub dhau los yog muaj kev sib koom ua ke me me. |
| Kaw slump | Yog tias cov duab tawg tag, qhov sib tov yog dej dhau thiab yuav xav tau kev sib xyaw. |
Cov chav kawm ntawm pob zeb slump
Raws li kev soj ntsuam, kev ntsuas qhov sib txawv ntawm qhov siab ntawm lub khob hliav qab thiab qhov siab ntawm slumped qhob yuav tsum tau ua. Txoj kev no, koj tuaj yeem faib cov kev poob qis raws li European qauv (BS 8500).
| Chav kawm | Ntau yam (mm) | Lub hom phiaj poob siab (mm) |
|---|---|---|
| S1 | 10 – 40 | 20 |
| S2 | 50 – 90 | 70 |
| S3 | 100 – 150 | 130 |
| S4 | 160 – 210 | 180 |
| S5 | 210 + | 220 |
Txhua ntawm tsib chav kawm qhia txog tus nqi poob qis, thiab txhua chav kawm tau siv rau kev siv sib txawv nyob ntawm qhov sib xws. Qee qhov xwm txheej, yog tias qee chav kawm ntawm kev poob qis tsis tau ua tiav rau daim ntawv thov koj siv nws rau, nws yuav xav tau remixing. Nyob rau hauv txhua rooj plaub, tus kws tshaj lij cov khoom lag luam yuav tuaj yeem muab tswv yim.
