摘要
通过综合物探技术和三维激光探测技术,对桩侧和桩端的重大地质灾害源进行了精确探查,对岩溶、裂隙等地质灾害源进行了定位、定量精细化探查,同时对超前钻、物探等勘察结果进行了验证,有利于避免超前钻“一孔之见”的弊端,从而解决了单一物探探测解译误差大的缺陷,为岩溶区隐伏溶洞处治、桩基施工和设计提供了重要依据。
Through the comprehensive geophysical exploration technology and three-dimensional laser detection technology,the major geological disaster sources at the pile side and pile end are accurately explored,the sources of geological hazards such as karsts and fissures are located and quantitatively refined explored,and the exploration results of advanced drilling and geophysical exploration are verified.The disadvantages of“one hole view”of advanced drilling are avoided,and the defect of large interpretation error of single geophysical exploration is solved.It provides an important basis for the treatment of hidden karst cave,pile foundation construction and design in karst area.
