摘要
结合典型工程实例,介绍了佛山市某工程基坑在复杂环境下采用不同支护桩间距均取得了良好的支护效果,验证了即使在深厚砂层区支护桩间距亦可适当加宽;采用该支护形式可确保基坑安全,节省工程造价,对复杂周边环境下有深厚砂层的类似基坑工程,具有借鉴作用。
Based on a project in Foshan City,this paper introduces a foundation pit which has achieved good supporting performance by adopting different spacing of supporting piles under complex environment,and verifies that the spacing of supporting piles can be appropriately widened even in the area of deep sand layer.Adopting this type of support can ensure the safety of foundation pit,reduce project cost,and be applied to similar foundation pit projects with deep sand layer under complex surrounding environment.
