承台式抗滑桩受力机理及其在护岸工程中的应用

Stress Mechanism of Platform-type Anti-sliding Pile and Its Application to Revetment Engineering

承台式抗滑桩是用承台连接前后两排桩可抵抗大滑坡推力的支挡结构,分析了承台式抗滑桩支挡边(滑)坡的作用机理,根据其受力特征,可以滑面为界将其分为上下两个部分计算分析,通过理论分析和工程设计,根据工程实例,提出可按在滑坡推力作用下的横向弹性地基约束的空间刚架模型分析上半部分(受荷段)结构内力,并对实际工程进行了优化设计。

Platform-type anti-sliding pile is a retaining structure with a back pile and a corresponding anterior pile firmly connected by a platform at the top of the anterior pile. This paper analyzes the acting mechanism for platform-type anti-sliding pile to retain side slop, proposes that according to stressing features, the pile can be divided into two parts to be calculated and analyzed by taking the sliding surface as the boundary, based on theoretical analysis and engineering design, according to engineering practice, points out that space rigidity framework model with horizontal elasticity strata constraint under the action of landslide thrust can be used to analyze the internal structure force and implement optimized design for practical projects.
