深基坑悬臂式支护桩设计计算的改进
摘要:悬臂式支护桩的设计,以静力平衡法计算较为简单明确,且安全可靠。从土层抗剪强度指标粘聚力c、内摩擦角φ值的选用谈起,其次为作用在桩上的侧土压力计算的改进与水压力的分析,并对悬臂式支护桩的结构计算作了系统的阐述和导出了比较实用的公式,最后举一工程实例以供读者参考。
Abstract:The statical equilibrium method is the simpler and clearer one for design of cantilever retaining pile, and safe and reliable. Firstly,the selection of soil shearing strength indexes, such as the cohesion c and the internal friction angle φ, is discussed. Secondly, the improvement on the laternal earth pressure and the analysis of water pressure acting on pile are introduced. Thirdly, the structural calculation of cantilever retaining pile is expounded systematically, and some more practical formulae are formed. Finally an example is given reader to refer.
