为系统化总结软土地基超长桩静载试验反力装置设置经验,结合深圳某软土地基超长桩项目,根据现场实际情况提出了针对三种不同桩型超长桩的静载试验反力装置设置技术方案,该方案分别从地基处理设计、复合地基承载力计算、复合地基变形计算、锚桩设计、反力架系统及压重平台设计等方面进行分析验算,通过该项目三种桩型中的某三根桩的静载试验曲线可以看出,该技术方案切实可行。
In order to systematically summarize the experiences of setting up the reaction device of the static load test of super long pile in soft soil foundation and the super long pile project of a soft soil foundation in Shenzhen, the static load test against three different types of pile is put forward according to the actual situation in the field. The device is equipped with technical scheme. The program analyzes and calculates from the foundation treatment design, the bearing capacity calculation of composite foundation, the deformation calculation of composite foundation, the design of anchor pile, the reaction frame system and the design of ballast platform. Through the three kinds of pile Static load test curve of some three piles in the model can be seen that the technical solution is feasible.
