综合技术手段在岩土工程中的应用——以贵州复杂场地某高层商住楼岩土勘察为例

APPLICATION OF COMPREHENSIVE TECHNOLOGY IN GEOTECHNICAL ENGINEERING -- Taking Guizhou complex site for a tall building in geotechnical investigation as an example

传统的岩土勘察方法,在复杂地质条件下无法迅速准确查清地质特点,尤其是在贵州喀斯特岩溶地区,利用单一的常规勘察手段无法解决复杂问题,特别是当遇到岩溶、断层破碎带发育时;在复杂场地岩土工程勘察过程中利用物探等综合勘察手段,可以迅速查清岩溶发育,断层破碎带的分布范围及其埋深。本文就高密度电法在贵州省某高层商住楼岩土勘察工程中的具体应用效果,综合讨论在该类型场地综合应用岩土勘察工作的常规钻探和物探方法,为岩溶发育地区的岩土工程勘察积累经验。

The traditional method of geotechnical investigation, under complex geological conditions can quickly and accurately find out the geological characteristics, especially in Guizhou Karst karst area, the use of conventional reconnaissance means singleunable to solve complex problems, especially when it comes to karst, fault fracture zone development; use of geophysical comprehensive investigation in the process of complex geotechnical engineering investigation and can quickly identify the karst, fault fracture zone and its buried depth distribution range.In this paper, the high density resistivity method in Guizhou province for a tall building in geotechnical investigation results of practical application in engineering, the comprehensive discussion of exploration work in this type of site comprehensive application of rock and soil drilling and geophysical methods, and accumulate experience for geotechnical engineering in karst area survey.
