桩基优化设计经济效益分析

Analysis on Economic Benefit of Optimal Design of Pile Foundation

分析岩土工程勘察报告中所揭示的地基土层特性,根据所掌握的大量桩基工程检测试验数据、沉降观测实测数据,对桩周(端)地基土的受荷性能以及基桩工作性状进行研究,通过静载荷试验的实际桩基承载能力,分析推导出优化地基土桩基设计参数。据此优化带来了一定的经济效益。

Analysis is made on the characteristics of foundation soil layers revealed in the investigation report of geotechni-cal engineering and based on a large amount of data from pile foundation engineering testing and settlement observation, the study is carried out on the loading performance of foundation soil around （ end） pile and working properties of foundation pile.By the actual bearing capacity of pile foundation in static load test, the optimal parameters of soil for pile foundation design are derived with economic benefits.
