原位测试确定道路基底承载力方法研究

Study on Method of Original Test in Determining Ground Bearing Capacity

总结了潭邵高速公路现场进行的几种原位测试方法 ,根据现场原位测试结果建立了轻便触探击数 N1 0 与原状土十字板剪切峰值强度 Cu和容许承载力标准值 fk之间的相关关系 。

The several original test methods conducted in the site of Tan Shao Expressway are summaried. And based on the site original test results, the pertinent relationship of slight drilling blows N 10 and original soil cross slab shearing peak value strength C u and standard allowable bearing capacity f k are set up. All of which can be applied to judgement of ground bearing capacity of similar soft soil for reference.
