摘要
在岩溶发育地区,查明综合管廊结构影响范围内岩溶的发育程度至关重要。跨孔地震CT技术在岩溶勘察中得到越来越广泛的应用,但在综合管廊的岩溶勘察中鲜见报道。本文依托深圳市16号地铁线综合管廊工程,对跨孔地震CT技术在综合管廊岩溶勘察中的应用进行研究。结果表明,采用跨孔地震CT对综合管廊岩溶进行勘察是可行的,受地震波走时观测误差的影响,跨孔地震CT推测岩溶结果与钻探直接揭露情况存在一定差异,但总体结果基本一致。
In karst developed areas,it is crucial to identify the degree of karst development within the influence range of the comprehensive pipe gallery structure.Cross hole seismic CT technology is increasingly widely used in karst exploration,but few relevant literature has been seen in the karst exploration of comprehensive pipe gallery.Based on the comprehensive pipe gallery project of No.16 subway line in Shenzhen,this paper studies the application of cross hole seismic CT technology in the karst exploration of comprehensive pipe gallery.The results show that it is feasible to investigate the karst of the comprehensive pipe gallery by cross hole seismic CT.Affected by the observation error of seismic wave travel time,there are some differences between the karst results of cross hole seismic CT and the direct drilling exposure,but the results are generally consistent.
