摘要
喀斯特地貌区桩基施工中常出现多次穿越溶洞情况,处理方法选择不当,易发生漏浆、卡钻、埋钻、塌孔,严重时还会出现钻机倾覆、地面沉陷等事故。对于桩基周围有建筑物时,桩基穿越溶洞施工的关键技术,不仅关系到工程质量,还影响建筑物结构安全性。
In the construction of pile foundation in karst geomorphic area,there are often many cases of karst caves.The treatment methods are improperly selected,and it is prone to slurry leakage,stuck drilling,buried drilling and collapse.In severe cases,there will be accidents such as overturning of the rig and ground subsidence.When there are buildings around the pile foundation,the key technology of pile foundation crossing the karst cave construction not only affects the quality of the project,but also affects the structural safety of the building.
