某厂房预制桩单桩承力的综合分析

A comprehensive analysis on sustaining strength of previously made single stake of a certain workshop

在桩基础设计中,单桩承载力的取值是一个非常重要的参数,其取值准确与否直接关系到建筑物的安全及基础工程的投资,在分析工程地质勘察资料的基础上,充分利用单桩静载试验结果,在单桩静载试验的基础上,通过对冰水沉积的砂卵石层做为桩端持力层的实例,分析计算了某连铸厂房柱基础的单桩承载力,建立了估算桩顶沉降量的经验公式,提出了比较可靠、经济的桩基础设计方案。

On the basis of stake design, the values of the single stake to sustain are very important parameters. And the accuracy of them will directly results in the building safety and basic project investment. With the analysis of the project geology reconnoiter, the experimental results of the single stake are made full use of. After the experiment of the single stake to immobile sustain and the instance of icy-water sedimented sand scree layer as the sustain layer of the stake tip, the sustaining strength of the single stake of one certain stake basis is analyzed. And the experience formula of assessing sedimentation amount of the stake is established, thus a reliable and economical stake design plan is proposed.
