现代深部岩溶研究进展与展望

Evolvement and Expectation of Research on the Modern Deep Karst

现代深部岩溶问题是随着工程建设向复杂场地延伸而逐渐显现,由它带来的一系列地质工程问题对越岭隧道工程具有极强的控制性和危害性,如渝怀线圆梁山深埋特长越岭隧道工程出现的高压突水、突泥问题,既控制了工程的施工难度,又是一个极具挑战性的理论难题。综述了现代深部岩溶相关概念、发育类型、发育特征、形成机制等方面国内外研究现状,勾画了现代深部岩溶研究今后的重点,主要包括现代深部岩溶概念的厘定、现代深部岩溶工程地质分类及特征、现代深部岩溶受控因素、现代深部岩溶发育机制及演化、现代深部岩溶对越岭隧道工程控制作用等几方面的研究。

The problem of modem deep karst is obvious with the development of engineering construction which brings up a series of geology engineering problems to the construction of tunnel. For example, the problem of high pressure water gushing and mud outburst in the construction of great deep buried Yuanliangshan tunnel in Yuhuai railway, which is a challenging problem in the theory, controlled the construction difficulty. The research actuality on relative conception, development type, characteristics and form mechanism of the modem deep Karst is also discussed in this paper which sketched the research keystone of the modem deep Karst including the research on conception, engineering geology classification and characteristics, controlling factors, development mechanism and evolvement, controlling on the tunnel construction of the modem deep Karst, and so on.
