摘要:
为了研究大连多岩溶区的复杂地质条件对基坑开挖的影响,运用有限差分软件FLAC3D对不同溶洞位置的基坑进行模拟,得到位移变化规律。同时利用单元安全状态评价指标ZSI(Zone State Index)对不同溶洞位置下基坑周围土体进行评价,针对影响较大区域溶洞提出合理的溶洞处理方案。研究结果表明:溶洞对基坑稳定性影响程度由大到小依次是被动区、过渡区、主动区。针对被动区溶洞采取开挖前注浆处理,通过对大连地区深基坑进行数值模拟确定的不同溶洞位置对基坑影响程度具有一定的指导意义,可为岩溶地区深基坑工程的设计与施工提供参考。
Abstract:
In order to study the influence of complex geological conditions on foundation pit excavation in multikarst areas at Dalian, the finite difference software FLAC3D was used to simulate foundation pits in different positions of karst caves and the displacement variation law was obtained. At the same time, the unit safety evaluation index ZSI( Zone State Index) was used to evaluate the soil around the foundation pit at different karst cave locations, and a reasonable karst cave treatment scheme was proposed for the karst caves in the regions with larger influences. The results show that the influence degree of karst cave on the stability of the foundation pit is the passive zone, the transition zone and the active zone. Preexcavation Grouting treatment is adopted for the passive zone caves. Through the numerical simulation of the deep foundation pit in Dalian, the influence of different karst caves locations on the foundation pit has certain guiding significance, which can provide reference for the design and construction of the deep foundation pit in karst areas.
