| 摘 要： | 静力触探技术经过70余年的发展及日趋完善，其操作简单，智能化程度高，是岩土工程勘察常用的原位测试手段之一。静力触探基本原理就是通过探头传感器实现一系列量的转化，并由仪器记录下来，达到测定土强度和其它指标之目的。本文一方面重点论述了静力触探技术在黄土地区勘察中的应用：根据地区黄土地层特点和经验建立了确定地基土承载力的经验公式及其它有关力学参数；详细地论述了如何依据静力触探参数判别土的类别、划分地层界线、确定地下水位埋深和地下洞穴等。特别是依据静力触探参数和曲线形态判别地下洞穴和确定地下水位是本领域的创新和发展。

| Abstract: | Through development about 70 years, CPT technique that is one of the methods of in-situ test in geotechnical investigation and surveying becomes more and more perfect. The operation of CPT is simple and the intellectualization of CPT is high. The basic theory of CPT is to test strength and other mechanic parameters of soil through sensor in sounding cone to finish a series of change of measurement, then the instrument records data. The application of CPT technique for engineering in loess area is mainly studied in this paper after disclosing basic theory and operative method of CPT. According to the characteristic and experience of loess ground, the formula to determine bearing capacity of ground and other related mechanic parameter is established. How to apply parameter of CPT to classify soil, determine depth of groundwater level and underground cave is expounded. Particularly, according to parameter and characteristic of curve of CPT to detect groundwater level and underground cave brings forth new ideas in the field. |
