北京地区土工试验成果及综合分析

The Comprehensive Analysis of the Soil Test Results in Beijing Area

通过对北京地区各类上的多年试验成果中的物理指标、力学指标的综合分析,利用数据统计、回归分析、经验修正等方法,绘制了一些物理性质指标和力学性质指标的关系图,总结出了一些规律性的认识和结论。利用这些规律和结论可以对土工试验成果中出现的一些异常现象做出正确分析和判断,为岩土工程勘察设计提供合理和准确的试验数据,以保证建设工程的质量和安全。

Through the comprehensive analysis of the physical indexes and the mechanical indexes used in the soil test results of all kinds of soils in Beijing area, some relationship diagrams are drawn between the indexes of physical property and the indexes of mechanical property based on the data statistics, regression analysis and empirical correction. Then, some regular cognitions and conclusion are summarized. Taking advantage of the regulations and conclusions, we can make correct analysis and judgment to some abnormal phenomena in the soil tests, offered the more rational and more accurate test data for the geotechnical engineering survey and design,in order to assure the quality and safety of the engineering construction.
