[摘要]在分析基坑周邊環(huán)境條件、工程地質(zhì)條件的基礎(chǔ)上,采用一種新型的球型漿囊袋注漿錨桿,選用排樁錨桿聯(lián)合支護(hù)體系對某位于深厚淤泥質(zhì)土層中的基坑進(jìn)行支護(hù)。對這種新型的錨桿進(jìn)行了抗拔力試驗(yàn),對圍護(hù)體進(jìn)行了水平位移監(jiān)測。試驗(yàn)和監(jiān)測結(jié)果顯示,采用球型漿囊袋注漿錨桿的排樁錨桿聯(lián)合支護(hù)體系在深厚淤泥質(zhì)基坑中的應(yīng)用是可行,這種錨桿的作用效果是顯著的,用其替代排樁內(nèi)支撐體系中的內(nèi)支撐,不但節(jié)省了工程造價(jià)還給土方開挖帶來了很大的便利。

Abstract: Based on the analysis of the surroundings around the foundation pit and the engineering conditions, a new technology of slurry pocket anchor rod was employed. The combined shoring both soldier piles and slurry pocket anchor rod was used for this foundation pit construction in the silt clay, then put-out force test of the new anchor rod was conducted and the horizontal displacement of enclosure was monitored. Monitoring result shows the combined shoring both soldier piles and slurry pocket anchor rod in the silt clay foundation pit is practicable, using the slurry pocket anchor rod to inplace of the internal bracing structure in the soldier piles can reduce investment outlay and bring convenience for excavation of earth.
Keywords: silt clay; anchor rod; combined shorting; load-displacement curve
