摘要
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 counterforce device setup experience for static load test of super-long pile in soft soil foundation, in combination with of a Shenzhen project of the super long pile in soft soil foundation , the counterforce setup technology schemes for static load test of three different type of super-long piles were put forward according to the actual site conditions. The scheme was analzyed and checked in terms of foundation treatment design, calculation of composite foundation bearing capacity, calculation of composite foundation deforma- tion, anchor pile design, reaction frame system and ballast platform design etc. Through the static load test curves of the three different type of super-long piles in the project,it can be seen that this scheme is feasible.
