黏土夹砂礓地层和基岩裂隙中基坑降水设计

Design of Foundation Pit Dewatering in Clay with Gravel Stratum and Bedrock Fissure

基坑降水设计对深基坑施工具有重要意义,直接影响基坑自身、周边环境的安全。本文通过对徐州地铁2号线九里山站水文地质特征、周边环境进行分析,阐述在黏土夹砂礓地层和基岩裂隙中具体的降水设计思路与对策,确保降水效果,保证基坑及周边环境安全,为类似工程提供借鉴。

The design of foundation pit dewatering is of great significance to the construction of deep foundation pit, which directly affects the safety of the foundation pit itself and the surrounding environment. This paper elaborates the design ideas and of precipitation in clay with gravel stratum and bedrock cracks based on analysis of hydrogeological features and surroundings of Jiulishan Station in Xuzhou Metro Line 2. This study helps to ensure the effect of precipitation and provide security for foundation pit and its surroundings. It can also be referred to similar projects.
