Ua rau deformations ntawm lub hauv paus

Cov kev siv ntawm tej lub tsev pib nrog lub hauv paus. Muaj ntau ntau hom ntawm cov me nyuam yaus (sawb, pawg, phaj, thiab lwm yam), tab sis tag nrho lawv pab ib lub hom phiaj - los hloov lub load los ntawm qhov kev siv thaj av. Tab sis muaj nyuam qhuav tau ib qho kev nthuav sib - cov neeg muaj txoj siav rau designers yuav tau txais kev them nyiaj thiab tsim, thaum tsis paub lub geological qauv thiab thaj chaw ntawm cov av, uas yuav tau tsev. Tej zaum lub tsev yog tsim nyog ntau lub xyoo thiab tsis muaj dab tsi tshwm sim, thiab tej zaum, thaum yog thaum tom qab ib tug ob peb xyoos, mam li nco dheev pom tej kab nrib pleb, cov qhov rooj yog tsis qhib, thiab lwm yam Ib tug yog vim li cas feem ntau cov lus dag nyob rau hauv cov yam ntxwv ntawm geological tej yam kev mob ntawm kev tsim kho chaw, precisely ntau nyob rau hauv cov txheej txheem uas coj qhov chaw nyob rau hauv lub qab daus thiab av sis (tsawg-zoo cov ntaub ntawv thiab builders yuam kev ib sab). Cia peb kawm lawv nyob rau hauv kom meej.

Feem ntau cov feem ntau muaj cov nram qab no dab: sis tsis ncaj dej nag, te heave, dej nyab. Tsis tshua cai Suffusion thiab txawm rarer - landslides. Qhov no yog tsis yog ib tug ua tiav daim ntawv teev yuav mus rau hauv thiab nyob, tab sis cia saib lub yav tas los hais dab, lawv ua thiab yuav ua li cas nrog lawv.

Sis tsis ncaj precipitates tshwm sim vim hais tias ntawm qhov sib txawv load kabmob muaj peev xwm ntawm xau nyob rau hauv tib yam loads. Ib tug piv txwv ntawm ib tug kaum ntawm lub tsev raws li ib tug tuab zoo ua qoob, thiab nyob ib tug thib ob lub kaum sab xis - lens peat. Nws yog pom tseeb tias lub tsev yuav qaij ntawm no lens. Qhov teeb meem yog solved (los yog es tsis pub) los ntawm kev thov competent tsim ntawm lub hauv paus rau lub hauv paus ntawm suav uas yuav tsum cia siab rau cov ntaub ntawv geotechnical soj ntsuam.

Frost heave tshwm sim xwb nyob rau hauv clayey thiab silty xau. Yuav kom tshem tawm nws cov nyhuv rau lub hauv paus, tso rau hauv lub tob yuav tsum muaj tsawg tshaj li tus khov tob thiab sab nto ntawm lub hauv paus yuav tsum tau insulated los ntawm cov av los mus tiv thaiv khov. Lwm embodiment - xuab zeb airbag 50 cm tuab thiab tib sab kev rho tawm.

Dej nyab - tus txheej txheem ntawm av theem sawv mus rau ib tug tseem ceeb heev theem. sab nrauv waterproofing yog siv rau kev tiv thaiv. Nws yuav tsum tau muab sau tseg tias nyob rau hauv av nplaum xau feem ntau tsim perched, li ntawd, txuag rau waterproofing yog tsis tsim nyog.

Suffusion - tus txheej txheem ntawm cov neeg kho tshuab hloov lwm lub tsev av hais av. Nws muaj xwb nyob rau hauv inequigranular sands. Suffosion sib ntaus sib tua ib qho nyuaj, yog li nws yog qhov zoo tshaj plaws los mus muab ib lub hauv paus uas yog tau kom lub tsev tsis deformation, txawm nyob rau hauv lub xub ntiag ntawm me me voids hauv qab nws. Qhov zoo tshaj plaws kev xaiv - qhov cub.

Landslides - ib tug kuj tsis tshua muaj, tiam sis insidious geological dab. Lawv tshwm sim thaum lub steepness ntawm tus nqes hav ntawm los ntawm 3 degrees, ntawm qhov tob ntawm lub capture yuav tsum yog los ntawm ob peb lub kaum centimeters mus rau pua pua ntawm meters. Yog hais tias koj lub tsev yog ua rau ib tug nqes hav, nws yog tsim nyog rau qhov chaw nyob nyob rau hauv ib tug loj chaw ua hauj lwm thiab ua ib tug muab xam of stability.

Yog li ntawd yuav tsum qhia: tag nrho cov nyob nrog cov me nyuam yaus teeb meem tshwm sim vim tsis txaus txoj kev tshawb no ntawm lub geological qauv, los yog txawm cov tsis muaj ntaub ntawv hais txog nws. Tsis txhob skimp on cov kev tshawb fawb. Yog hais tias lub hauv paus - lub hauv paus ntawm lub tsev, cov daim ntawv ntsuam xyuas - lub hauv paus ntawm lub hauv paus tsim. Lub xam yuav siv sij hawm mus rau hauv tus account thiab physico-mechanical thaj chaw ntawm av (tag nrho cov deformation modulus, ceev, thiab lwm yam) thiab qhov xwm ntawm tus geological seem (lub hom ntawm cov av, lawv muaj peev xwm, tshwj xeeb tshaj yog tej txaj chaw). Kuaj muab cov lus qhia rau hauv qab av, uas yog tej zaum kuj tseem ceeb heev rau cov kev xaiv ntawm lub hauv paus hom.
