综合分析方法在地层判识中的应用

Application of Comprehensive Analysis Method in Stratigraphic Identification

在第四纪沉积中,某些沉积相依靠单一的勘察方法较难识别,针对这一难点,我们利用钻探、井探、物探等多种手段,对某一变电站工程进行了综合勘察,最后结合物理力学指标,标准贯入试验和波速测试等原位测试指标,并采用静力触探数据、和电法测试数据等多个方面的资料对比分析,以达到综合划分地层,判定工程力学性质,合理进行岩土工程评价的目的。

In the Quaternary, it is hard to recognize sedimentary facies rely on a single method, for this difficulty, we use drilling, exploration wells, geophysical exploration and other means to carry out a comprehensive survey on a substation project, Finally, the in-situ test indexes, such as physical mechanics index, standard penetration test and wave velocity test, combine with the data of CPT and resistivity test data in order to divide the stratum comprehensively and determine the engineering mechanics properties, evaluate the geotechnical engineering reasonably.
