旋转触探作为一种新型原位测试技术已通过生产实践检验并在岩土工程勘察中逐步推广,然而有关其工程化应用问题尚有待完善。本文通过在京津城际线、京沪高铁线桩基试验点、邯郸至黄骅铁路线等地开展现场旋转试验,并将所得旋转触探试验结果与相应点位的静力触探及钻孔化验资料进行对比分析,初步总结出应用旋转触探试验结果划分地层、确定土的定名方法的一些规律,所得结果为推动旋转触探工程化应用提供了重要依据。
As a new type of in-situ testing technology, rotary touches have been verified through production practice and gradually popularized in geotechnical investigation. However, the application of rotary touches remains to be improved. This article through the Beijing-Tianjin inter-city line, the Beijing-Shanghai high-speed railway line pile foundation test point, Handan to Huanghua railway line and other places to carry out on-site rotation test, and the results of the rotary contact probe and the corresponding point of static penetration and drilling The contrastive analysis of the experimental data and preliminary summarizes the application of rotary touches the test results to divide the strata, to determine some of the laws of the soil naming method, the results provide an important basis for promoting the engineering application of rotary touches.
