Kev tshawb pom ntawm lub hauv paus kev kho mob nyhuv

1.Hloov txoj kev filling

Tom qab hloov lub hauv paus txoj kev, lub nplhaib riam txoj kev, static touch test, lub teeb dynamic touch test thiab standard penetration test yuav tsum tau siv los ntsuam xyuas cov nyhuv ntawm lub hauv paus kev kho mob. Thaum lub sijhawm kuaj, qhov ntsuas qhov ntsuas yuav tsum nyob ntawm 2/3 ntawm cov tuab ntawm txhua txheej, thiab cov phaj thauj khoom tsim nyog yuav tsum raug xaiv los siv cov khoom thauj mus rau lub hauv paus ua ntej, thiab tom qab ntawd cov qauv ntsuas yuav tsum tau teem caij. Lub hauv paus pit yuav tsum tsis pub tsawg tshaj 1 taw tes rau 10 ~ 20m; thaum lub hauv paus zawj yuav tsum tsis txhob tsawg tshaj li 1 qhov chaw kuaj pom ntawm 50 ~ 100 ㎡.

2. Muaj zog ramming txoj kev

Tom qab lub dynamic compaction txoj kev ntawm lub hauv paus, yuav tsum ncua sij hawm mus rau lub hauv paus kev ntsuam xyuas zoo, xws li nyob rau hauv situ xeem (tsav load xeem thiab sab hauv tsev geotechnical xeem, thiab tus naj npawb ntawm nrhiav kom tau cov ntsiab lus yuav tsum tau raws li nyob rau hauv lub complexity ntawm lub site thiab qhov tseem ceeb. lub tsev los txiav txim, feem ntau txhua lub hauv paus ntawm kev tshawb nrhiav cov ntsiab lus yuav tsum tsis pub tsawg tshaj 3, yog tias lub hauv paus yog qhov nyuaj, yuav tsum tsim nyog kom nce cov ntsiab lus tshuaj xyuas tib lub sijhawm, dynamic touch test, static touch test, cross plate xeem, load test, wave speed test, side pressure meter test thiab offset shovel side expansion test thiab lwm yam kev ntsuam xyuas yuav tsum tau ua, thiab tus naj npawb ntawm cov ntsiab lus tshawb pom yuav tsum tsis pub tsawg tshaj 3 lub ntsiab lus, thiab tsis pub tsawg dua 1% tus naj npawb ntawm cov ntsiab lus pier.

3.precompression

Tom qab lub hauv paus, cov nyhuv kho yuav tsum tau sim. Thaum lub sijhawm kuaj, cov chaw sawv cev yuav tsum tau tshwj tseg rau hauv qhov chaw prepressure, shear lub zog kuaj ntawm qhov sib txawv ntawm qhov tob thiab cov av extraction rau sab hauv tsev, thiab cov txiaj ntsig zoo ntawm lub hauv paus kev txhawb nqa yuav tsum raug txiav txim raws li kev tiv thaiv kev ruaj ntseg ntawm hydrochloric acid foundation. Lub tshuab nqus tsev-preloading txoj kev yuav tsum tau sim ntawm ntau theem thiab tom qab lub tshuab nqus tsev rho tawm.
