摘要
临河区域受河水侧向压力、季节性水位波动及强透水层影响,地基土呈现含水量高、压缩性大、抗剪强度低等特性,这对基坑底板的稳定性与防水性能提出了更高要求。文章对临河区域深基坑底板施工展开研究,结合工程实例,对比分析临河区域与普通地段深基坑底板的施工特点,明确相应施工要求,从地基处理、防水施工双重维度入手,提出地基处理方法和防水措施,旨在有效控制地基沉降、降低渗漏风险。
Riverside area is influenced by the lateral pressure from river water,seasonal water level fluctuation and strong permeable layer,and its foundation soil has the characteristics such as high moisture content,high compressibility and low shear strength,which puts forward higher requirements for the stability and waterproof performance of the foundation pit floor.This paper studies the deep foundation pit floor construction in riverside areas.Combined with engineering examples,the construction characteristics of deep foundation pit floor in riverside areas and ordinary sections are compared and analyzed,and the corresponding construction requirements are clarified.Starting from the dual dimensions of foundation treatment and waterproof construction,the foundation treatment methods and waterproof measures are put forward,aiming at effectively controlling foundation settlement and reducing leakage risks.
