Preface

Karst areas are distributed in Southwest China, accounting for nearly 1 / 3 of the total area of Southwest China. The landform of karst area is complex, and the development of karst has the characteristics of uncertainty and concealment. Therefore, it is very difficult to carry out the geological survey of engineering construction in karst area. Karst may induce the corresponding geological disasters, which brings not only the construction difficulties on the terrain, but also need to be taken seriously in the specific engineering construction.

  Karst is the general name of some phenomena produced by the geological process, which is dominated by chemical dissolution and supplemented by water mechanical action, such as erosion and undercutting. The landform formed by karst is called karst landform. At present, many researchers have carried out various researches on it, and have made good achievements in some fields. However, as our country builds more and more projects in karst areas, there are more and more problems encountered in engineering surveys. Although engineers and technicians have constantly summed up a lot of experience in the process of surveying, the geology and landforms of karst areas are complex and diverse, and the geological survey technology needs further research.

  It is very necessary to conduct effective surveys of engineering construction geology in karst areas. The development of karst in karst areas is a very troublesome problem, and its uncertainty and concealment add to the difficulty of technical surveys. Its uncertainty and concealment make technical surveys more difficult. Therefore, under realistic geological and geomorphic conditions, when we carry out engineering construction in karst areas, we must combine the corresponding geological survey technology according to the specific work conditions. Only by understanding the relevant changes in the karst area in detail can we make a reasonable engineering construction plan. However, in the specific survey process, there are still many problems that will arise. These problems may have never been encountered before and cannot be solved with existing technology. In the face of this situation, we have to constantly strengthen the updating of technology and find out new technical methods, in order to better complete the engineering construction under the karst geological conditions. 

前 言

岩溶地区要分布在我国的西南地区，面积将近占了西南地区总面积的 1/3。岩溶地区的地形地貌比较复杂，岩溶的发育具有不确定性和隐蔽性的特征，因而在进行岩溶地区工程建设地质勘察的过程中，难度相当大。岩溶可能诱发相应的地质灾害，这就给工程建设带来了不仅仅是地形上的建设困难，还需要在具体的工程建设中认真的对待。
       岩溶是指水对可溶性岩石作用时，以化学溶蚀为主，水的机械作用冲蚀、潜蚀等为辅的地质作用所产生的一些现象的总称，也可叫做喀斯特。因为喀斯特作用形成的地貌，叫做喀斯特地貌。目前许多的研究者已经对其展开了多方面的研究，并组在一些领域取得了比较好的成就。但是，随着我国在岩溶地区建设的工程越来越多，在进行工程勘察时遇到的问题也就越来越多。虽然工程技术人员在勘察的过程中，也不断的总结了许多经验，但是岩溶地区的地质地貌繁杂多样，地质勘察技术还有待进一步的研究。
      对岩溶地区工程建设地质进行有效的勘察是非常有必要的。岩溶地区的喀斯特发育状况是一个非常麻烦的问题， 它的不确定性及隐蔽性加重了技术勘察上的难度。因此，在进行岩溶地区工程建设时，我们必须针对具体的工作情况，在现实的地质地貌条件下，结合相应的地质勘察技术，详细的了解和地岩溶的相关变化情况，从而做出合理的工程建设方案。但是，在具体的勘察过程中，还有很多问题会出现，这些问题有可能是以前我们从来都没有遇见的，用现有的技术也无法加以解决的。面对这种情况时，只有不断地加强技术方面的更新以及寻找出新的技术方法，我们才能够更好的完成岩溶地质条件下的工程建设。
