某二级公路岩溶发育特征及工程地质评价

KARST DEVELOPMENT CHARACTERISTICS AND ENGINEERING GEOLOGICAL EVALUATION OF A SECONDARY ROADS

拟建的某二级公路所在地区岩溶工程地质发育。通过分析该区岩溶发育的主要条件,调查各种岩溶形态的分布及发育特点,岩溶地下水的补径排特征来研究其岩溶发育特征,并对拟建公路的岩溶工程地质条件进行了评价和建议。研究表明,该区各种岩溶形态发育,针对某些岩溶病害,工程建设中应采取适当措施以减小其危害。

The karst geology is well developed in the area where the proposed secondary highway is located. The karst development characteristics are studied by analyzing the main conditions of karst development in this area, investigating the distribution and development characteristics of various karst forms, and the feature of recharge-runoff-discharge ground water. The karst geological conditions of the proposed highway are evaluated and corresponding suggestions have been given. The study shows that various karst morphologies are developed in this area. In view of some karst diseases, appropriate measures should be taken to reduce the hazards during construction.
