【摘要】 该文通过对茅台特大桥复杂不良地质构造的综合物探勘察成果分析,说明对于仅使用钻探手段很难查明的复杂不良地质构造,要根据不同勘察阶段,合理选择不同物探方法组合,才能得到满意的勘察效果。同时,认为物探资料解释不仅可以确定不良地质构造的地质界线,还可以根据所获得的岩土体物理参数,定性分析不良地质体的结构特征和稳定性。更多还原

【Abstract】 In this paper,through the analysis of the results of complicated and bad geological structure by comprehensive geophysical exploration techniques of Maotai super bridge site,it shows that it is difficult to find out the complicated and bad geological structure by single drilling method.Good effects are obtained by reasonably selecting different geophysical exploration methods in different survey phases.At the same time,the interpretation of geophysical data can not only determine the bad geological boundary,but also qualitatively analyze its structure features and stability based on the obtained physical parameters of rock-soil mass.更多还原
