PT型袖珍贯入仪在海岸带地区工程地质调查中的应用

Application of PT Type Pocket Penetrating Instrument in Engineering Geological Survey of Coastal Zone

摘要:

通过对莱州湾地区工程地质勘察中大量袖珍贯入试验与静力触探试验、标准贯入试验、土工试验数据的对比分析，采用数理统计方法，建立了PT型袖珍贯入阻力与静力触探试验指标、标准贯入试验击数、土的液性指数及压缩模量相关公式。为今后在海岸带地区工程地质勘察中，采用PT型袖珍贯入仪对岩心的现场贯入试验，及时准确地判定土的物理力学性质提供了依据。

Abstract:

Through comparison and analysis on a large number of pocket penetration test and static penetration test, standard penetration test and geotechnical test data in engineering and geological survey of Laizhou Bay area, by using mathematical statistics, relevant formula about PTtype pocket penetration resistance and static penetration test index, standard penetration test number, soil liquid index and the compression modulus have been established. It will provide basis for onsite penetration test of cores and timely and accurate determination of physical and mechanical properties of soil in engineering geological investigation in coastal area in the future.
