Xov xwm

1. Ua ib nrab ntim thiab ib nrab excavated roadbeds
Thaum tsim cov embankments ntawm txoj kab nqes nrog txoj kab nqes ntuj tshaj li 1: 5 hauv av, cov kauj ruam yuav tsum tau khawb ntawm lub hauv paus ntawm embankment, thiab qhov dav ntawm cov kauj ruam yuav tsum tsis pub tsawg tshaj 1 meter. Thaum txhim kho lossis kho txoj kev loj hauv theem thiab nthuav dav, cov kauj ruam yuav tsum tau khawb ntawm qhov sib tshuam ntawm qhov tshiab thiab qub embankment sau slopes. Qhov dav ntawm cov kauj ruam ntawm cov qib highway yog feem ntau 2 meters. Geogrids yuav tsum tau muab tso rau ntawm kab rov tav ntawm txhua txheej txheej ntawm cov kauj ruam, thiab ntsug sab confinement reinforcement nyhuv ntawm geogrids yuav tsum tau siv los daws qhov teeb meem ntawm kev sib hais tsis sib haum.

2. Roadbed nyob rau hauv cov cua thiab cov xuab zeb
Txoj kev taug kev nyob rau hauv cov cua daj cua dub thiab cov xuab zeb yuav tsum yog cov embankments qis, nrog rau qhov siab qhov siab feem ntau tsis pub tsawg tshaj 0.3M. Vim tias cov kev xav tau ntawm cov embankments qis thiab hnyav hnyav hauv kev tsim kho ntawm embankments hauv cov chaw cua thiab cov xuab zeb, kev siv cov geogrids tuaj yeem muaj kev cuam tshuam rau sab nraud ntawm cov khoom siv xoob, kom ntseeg tau tias txoj kev hauv tsev muaj qhov nruj thiab lub zog nyob rau hauv qhov siab txwv. kom tiv taus cov kev ntxhov siab ntawm cov tsheb loj.
3. Reinforcement ntawm cov av nyob rau sab nraum qab ntawm embankment
Kev siv ntawmgeogrid chavtuaj yeem ua tiav lub hom phiaj ntawm kev txhawb nqa lub nraub qaum ntawm tus choj. Lub geogrid chamber tuaj yeem tsim kom muaj kev sib txhuam txaus ntawm cov khoom ntim, txo qhov tsis sib xws ntawm txoj kev thiab cov qauv, txhawm rau txo qhov cuam tshuam thaum ntxov ntawm "bridge abutment jumping" kab mob ntawm tus choj lawj.

4. Kev kho ntawm Loess Collapse Roadbed
Thaum txoj kev loj thiab txoj kev loj loj dhau los ntawm qhov sib tsoo loess thiab loess seem nrog zoo compressibility, los yog thaum lub peev xwm tso cai ntawm lub hauv paus ntawm lub siab embankments qis dua lub siab ntawm lub tsheb sib koom tes load thiab embankment tus kheej hnyav, roadbed kuj yuav tsum tau kho raws li cov bearing muaj peev xwm yuav tsum tau. Lub sijhawm no, qhov superiority ntawm lubgeogridyog undoubtedly qhia.
5. Saline av thiab nthuav av
Txoj kev loj uas tsim los nrog cov av saline thiab expansive av adopts kev ntsuas kev txhawb nqa rau lub xub pwg nyom thiab txoj kab nqes. Qhov kev txhawb nqa ntsug ntawm kab sib chaws yog qhov zoo heev ntawm tag nrho cov khoom siv ntxiv, thiab nws muaj kev tiv thaiv corrosion zoo heev, uas tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm kev tsim txoj kev loj hauv cov av saline thiab expansive av.
