Av mechanics - lub hom phiaj ntawm ib tug khoom foundation

Av mechanics yog ib tug qhuab qhia uas kawm cov stability, lub dag lub zog thiab lim-kev nyuaj siab lub xeev ntawm av masses. Tsis tas li ntawd, cov av mechanics tshuaj xyuas tag nrho cov compressibility ntawm av khaubncaws sab nraud povtseg thiab lawv cov qauv-theem deformation thiab hu kuj hloov. Applied nqi ntawm qhov kev qhuab qhia yog siv nws cov kev tshwm sim nyob rau hauv tus tsim thiab kev siv ntawm ntau yam vaj tse.

Nrog kev tsim kho ntawm muaj, hydraulic thiab civil engineering, li zoo li hiav txwv, dej, vaj tse nyob, nroog, txoj kev thiab airfield siv siv cov ntaub ntawv thiab kev tshawb fawb tau muaj av mechanics. Me nyuam yaus, tsim thiab ua noj mus rau hauv tus account tag nrho cov tswv yim pom zoo ntawm cov kev disciplines, txawv zog, kev cia siab thiab durability. Tsis tas li ntawd, tseem ceeb ntawm cov av mechanics kawm thiab daws cov teeb meem ntawm deformation thiab resilience ntiaj teb engineering lug, qhov chaw siab tshaj, thiab lwm yam kev pab txhawb nqa cov phab ntsa.

Av Txhua yam - ib tug tsim nyog theoretical lub hauv paus rau qhov tseeb muab xam los ntawm bases thiab cov me nyuam yaus ntawm vaj tse. Kom tsim thiab kev siv ntawm cov me nyuam yaus lom zem ntau nyob rau cov kev ntsuam xyuas ntawm lub cev thiab txhua yam khoom thiab cov yam ntxwv ntawm cov av arrays ntawm muaj kuab xaiv ntawm bases thiab cov me nyuam yaus ntaus ntau thiab tsawg pab.

Los ntawm cov foundations ntawm qhov kev qhuab qhia tag nrho cov hom ntawm cov av, uas yog siv raws li lub hauv paus ntawm lub hauv paus ntawm ntau yam kev tsim kho tej yaam num yog muab faib ua tej yam ntuj tso thiab dag. Hauv pem teb arrays ntuj tshwm sim no yog hu ua ib tug natural puag, thiab cov neeg uas tau raug yav tas los fastened nyob rau hauv ntau txoj kev (silicification, carburizing, smolizatsiey, bituminization, thiab li ntawd.) - dag puag.

Nyob rau hauv nws cov keeb kwm xau yog dej num raws li nram no:

• Igneous. Tsim los ntawm geologic kev ua si ntawm cov ntiaj chaw (thiab cov cua txias ntawm lub lava uas).
• Metamorphic. Tsim raws li ib tug tshwm sim ntawm physico-tshuaj dab ntawm transformation ntawm igneous los yog sedimentary pob zeb nyob rau hauv cov nyhuv ntawm yam tseem ceeb xws li kub thiab siab.
• Sedimentary xau. Yog tsim los ntawm sedimentation.
• Dag. Lawv yog cov uas muaj thiab economic kev ua si.

Tus qauv ntawm cov av masses, uas kuj tshuaj xyuas qhov mechanics ntawm xau, yog reflected los ntawm nws cov kev ntxhib los mos thiab cov yam ntxwv yam ntxwv. Av qauv hu ua sau ua ib pawg loj yam ntxwv ntawm nws constituent hais, lawv zoo lawm, nto xwm, thiab lub quantitative piv ntawm lub Cheebtsam thiab lawv interconnections. Lub ntsiab yam ntawm av lug yog lumpy, nutty, platy, cloddy, scaly, silty mikroagressivnaya thiab lwm tus neeg. Lub ntsiab yam ntxwv xyuas pom tau hais tias cov dej-colloid hom thiab crystallization. Nws yog los ntawm cov tsis yog nyob ntawm seb cov kev xaiv ntawm lub hom foundation thiab tus ntsuam ntawm cov av loj rau qhov kev siv ntawm cov vaj tse ntawm no hom.
