【摘要】 目前软土地区基坑工程逐渐向着更大更深的方向发展,以烟台某软土基坑为例,采用桩锚支护体系结合被动区土体加固措施,通过管井与盲沟有效控制地下水,基坑监测数据表明该支护形式安全有效,保证了基坑边坡稳定。相对于内支撑体系,该支护形式为土方开挖与基础施工提供了便利条件,能够缩短工期,降低施工造价,对类似工程具有一定的参考价值。更多还原

【Abstract】 At present, foundation pit engineering in soft clay area is developing towards deeper and larger scale, taking a soft soil foundation pit in Yantai as an example, a pile-anchor support system combined with soil reinforcement measures in passive zone was adopted, besides, tubular well and blind drainage were used for dewatering. The foundation pit monitoring data show that the support system is safe and effective, and it can ensure the safety of foundation pit slope. Compared to internal bracing system, pile-anchor support system can provide convenience for soil excavation and foundation construction, moreover, it can shorten the construction period and reduce the construction cost, thus it can provide certain reference value for other similarly projects.更多还原
