庆阳地区湿陷性黄土工程力学特性研究

Study on Engineering Mechanical Properties of Collapsible Loess in Qingyang Area

随着西部大开发的进一步深化,越来越多的大厚度黄土场地被用作建筑场地,黄土特殊的工程力学特性将决定着工程的安全性与经济性。通过对甘肃庆阳陇东地区大量工程的试验数据统计分析,对湿陷性黄土的工程力学特性进行了研究:一方面对常规的物理力学参数进行了竖向的归纳总结,另一方面对黄土的力学参数与物理参数进行了横向分析对比,并得到相关的拟合关系式。可为庆阳地区工程的设计、咨询和施工提供参考。

As the western development goes further deep, more and more loess areas with large thickness are used as construction sites, in respect of which the special engineering mechanical properties of loess will decide the safety and economic efficiency of projects. With the statistical analysis on the test data from many projects in Qingyang, east region of Gansu Province, the collapsible loess＇ engineering mechanical properties was studied in two ways that, on the one hand, the conventional physical and mechanical parameters were generalized longitudinally; on the another hand, the mechanical parameters were compared with the physical ones laterally, then the fitting relation was obtained. For reference to the design, consulting and construction of projects in Qingyang.
