Research on Self-correlation Distance Character of Soil Based on Static Contact Exploration Method

论述了静力触探法的原理和应用范围.在递推空间法计算原理的基础上,推导了空间均值和空间标准差的计算式,得出比贯入阻力与变形指标、强度指标以及固结系数之间的自相关距离大致相同的结论.因此,在实际工程中可以利用静力触探法测得比贯入阻力,计算其自相关距离,从而间接求出其他土性指标的自相关距离.

This paper expounds on the principle and scope of apphcatlon oI the static contact exploration method. Based on the calculation principle of recursive space method, a conclusion is drawn that the self-correlation distances of specific penetration resistance with reference to deformation index and intensity index are approximately equal. Therefore, in practical engineering, static contact exploration method can be used to measure specific penetration resistance and calculate elf- correlation distances, and also self-correlation distances of other local indexes can be got indirectly.
