摘要
以蛇口邮轮中心基坑支护工程为例,研究在临海抛石地基上基坑支护方案的选用。通过现场试验获取施工参数并计算渗透系数,根据结果选择塑性混凝土咬合桩结构方案。介绍塑性混凝土咬合桩的受力特点和计算方法,以及在止水帷幕中的应用,并与实测资料相验证,证明了在抛石地基临海基坑中采用塑性混凝土咬合桩是安全可行的。
Taking the foundation pit supporting engineering of Shekou cruise center as an example, we study the selection of foundation pit supporting structure in the foundation of riprap backfill. Through obtaining the construction parameters and calculating the permeability coefficient through field test, we select the structural scheme of plastic concrete occluding pile.In this paper, we introduce the mechanical characteristics and calculation method of the plastic concrete bitten pile, and find out the practical design method with the measured data. The plastic concrete piles are proved safe and feasible in the riprap coastal foundation pit.
