岩溶发育地区隧道勘察设计经验与施工对策
Design experience and construction strategies of tunnel in karst development area
摘要
Abstract
The unascertained characteristics of the karst development and distribution, and the irregularity of the topography, caused the complexity of the karst tunnel surrounding rock condition. The karst tunnel design theory and construction technology has always been a hot and difficult issue in the field of tunnel engineering. Through considering the characteristics of the tunnel project, this article e-laborates the basic types of the karst development area, and summarizes the basic features and the influence on the tunnel engineering security of the typical karst landforms, which including grike, sinkhole, karst depression, blind valley etc. The common groundwater system of the tunnel engineering in the karst area was also generalized, and the survey and design principle in the karst area were taken.The design points and considerations in the preliminary design stage, in detailed survey and design stage and in construction design stage were pointed out. Based on several typical karst tunnel in Guizhou province, and by considering the problem found in the design, consultation and construction,this article summarizes the problems from the perspective of survey and design, aiming at providing reference for the tunnel design and construction in the karst area.关键词
