恭城县莲花镇枧头小学建设项目地质灾害特征及防治建议

Characteristics of Geohazards in Construction Project of the Jiantou Primary School,Lianhua Town,Gongcheng County and Their Control Measures

通过对广西恭城县莲花镇枧头小学建设项目周围地质灾害和隐患进行野外调研,查明主要地质灾害为岩溶塌陷,对其发育现状进行了评估,并预测岩溶塌陷对工程建设存在的地质灾害影响,提出了地质灾害防治措施,建议在主体施工建设前进一步查明地基是否有未发现的土洞或者软弱土存在,可采取灌浆、碎石充填等方法进行治理。同时建筑物基础施工做好地下水防水、排水工作,加强区内地下水动态监测。本文从对拟建项目的地质环境条件和地质灾害形成机理分析,工程建设中和工程建成后可能引发或加剧的地质灾害提供防治措施和参考依据。

The construction project of the Jiantou Primary School,Lianhua Town,Gongcheng County lies in a karst collapse area.This paper has a discuss on genetic mechanism of the karst collapse and estimates the influence of the karst collapse on the construction project and puts forward such control measures as groundwater dynamic monitoring,waterproofing,drainage,grouting and gravel filling.
