摘要
文章旨在研究特殊土地基的工程特性及地基处理方法,分析了数字化勘察技术的在岩土工程中的勘察过程。研究采用文献分析和案例研究的方法,对不同类型的土地基进行细致的研究。研究结果表明,膨胀土、软土和碎石土等特殊土地基各具特点,需要采用不同的地基处理方法。对于膨胀土,可以采用地基换填、土工合成材料加固和化学改良等方法进行处理;对于软土,可以采用前期排水固结、深层改良和悬臂式基础设计等方法进行处理;对于碎石土,可以采用动力碎石桩加固等方法进行处理。同时,遥感技术和地质雷达技术在城市地下岩土工程中具有广泛的应用前景,为勘察施工方提供了有效的技术支持。
The aim of this paper is to study the engineering characteristics of special land foundations and foundation treatment methods,and to analyze the survey process of digital survey technology in geotechnical engineering.The research uses literature analysis and case study methods to study different types of land foundations in detail.The results show that special foundations such as expansive soils,soft soils and gravel soils have their own characteristics and require different foundation treatment methods.For swelling soils,it can be treated by the methods of foundation replacement,geosynthetic reinforcement and chemical improvement;for soft soils,it can be treated by the methods of pre-drainage consolidation,deep improvement and cantilever foundation design;for gravel soils,,it can be treated by the methods of dynamic gravel pile reinforcement.At the same time,remote sensing technology and geological radar technology have wide application prospects in urban underground geotechnical engineering,providing effective technical support for survey and construction parties.
