摘要
通过钻孔、地质雷达及电磁波CT等物探技术对东风总干渠的蜘蛛洞渡槽施工中遇到的地质缺陷进行勘察,对成果进行对比分析研究,对地质构造定性,理清地层形成不整合成因,分析不整合地层岩溶发育机理及影响范围,着重研究缺陷分布范围,以及地质缺陷对渡槽结构的不利影响。本文内容体现了在地基缺陷分析方法上的创新,为同行今后对渡槽基础地质缺陷分析提供新的思路。
In the paper,geological defects encountered in Zhizhudong aqueduct construction of Dongfeng main canal are surveyed through drilling,geological radar,electromagnetic wave CT and other geophysical prospecting technology. The results are comparatively analyzed and studied. The qualitative geological structure is analyzed,stratigraphic unconformity formation reasons are sorted out. Unconformity formation karst development mechanism and influence scope are analyzed.Defect distribution range and adverse influence of geological defect on aqueduct structure are mainly studied. The contents in the paper are reflected on innovation of foundation defect analysis method,and new concepts are provided for analyzing aqueduct foundation geology defects by peers in the future.
