摘要
在填土、软弱可塑粘性土较深基坑中水位埋深约2.0m,开挖至8.0m深,周围危旧建筑较多,施工场地狭窄,基坑开挖近于直立,土质松散,易发生塌陷。在施工中采用了钢管桩、高压防渗板墙、槽内降水、槽外注水回灌,外加复合土钉墙支护措施,保证了基坑开挖。
In base pits with filled earth or soft plastic clay, it is quite difficult to construct for many reasons. In construction, supporting measures such as steel pipe pile, high-pressure impervious board wall were adopted, ensuring the excavation of base pits.
