摘要
在工程勘察中要求测试静止侧压力系数 K0 的日渐增多。多数单位采用侧压力仪做试验 ,由于仪器不完善、操作方法欠统一、K0 试验成果质量不高。文中通过实践分析了 K0 测值普遍偏小的原因 ,介绍在试验中的一些操作方法 ,提出改进侧压力仪结构的设想。
The test of lateral pressure coefficient K 0 at rest is required in prospecting. Most institutions conduct tests with lateral pressure apparatus. Because of the imperfection of instruments and the lack of standard operation,the quality of K 0 test is unsatisfactory. Based on practice the essay points out why the value of K 0 is generally on the small side, introduces some methods of operational, and puts forward suggestions on the improvement of the structure of lateral pressure apparatus.
