露天矿山地质工程软土地区岩土工程勘查要点分析

Analysis of Geotechnical Engineering Survey Points in Soft Soil Area of Open-pit Mine Geological Engineering

露天矿山地质工程常覆盖有软土层,软土的特点是可压缩性大、强度低、灵敏性高、透水性差,上述特点导致该类工程软土地区建筑存在地基变形量大,且不均匀沉降严重,地基稳定性低等特点,因而软土地区的岩土工程勘查质量对于保证工程质量具有重要意义。本文分别从地质调查测绘重点、外业勘探及原位测试工作、室内土工试验及软土勘查数据处理、岩土工程评价分析等四个方面出发,研究分析了该类工程软土地区的岩土工程勘查要点。本文的研究内容对于提高软土地区的岩土工程勘查工作质量具有一定的参考价值。

Open mine Geological engineering often covers soft soil layer,soft soil is characterized by high compressibility,low strength,high sensitivity,and poor permeability.The above characteristics lead to large deformation of the foundation in the soft soil area of this type of project,and the uneven settlement is serious.The stability of the foundation is low,so the quality of geotechnical survey in soft soil area is of great significance to ensure the quality of the project.This paper studies and analyzes the key points of geotechnical survey in soft soil areas of this kind of engineering from four aspects:key points of Geological Survey,field exploration and in-situ testing,indoor geotechnical test and soft soil survey data processing,and geotechnical engineering evaluation and analysis.The research content of this paper has certain reference value for improving the quality of geotechnical survey in soft soil area.
