某大型工程场地岩溶发育特征及工程地质条件评价

Distribution of Karst and Engineering Geology Conditions on A Project Site

摘要:

随着近年来在岩溶区修筑建筑物越来越多，岩溶给工程建设来了许多困难，探明岩溶区岩溶分布特征变得尤为重要。广东某大型工程场地在可研阶段发现大量溶洞，严重影响施工。本文从研究区的工程地质、水文地质等方面对岩溶的形成机制做详细阐述，通过物探和钻探方法，查明研究区岩溶分布和发育特征，并准确、合理地对场地的稳定性和工程建设的适宜性做出评价，也为岩溶区类似工程建设提供参考经验。

Abstract:

More and more buildings have been built in kars tareas in recent years and the constructions have encountered many difficulties of the karst. Identify karst distribution becomes important. A project site in Guangdong province found a large cave in the feasibility study stage, which affected the foundation construction seriously.This papers formation mechanism and distribution of the karst is analyzed from engineering geology,hydrogeology and many more. Based on geophysical,prospecting and borehole data,This papers find distribution of karst on a project site,and make a evaluation from stability site and construction suitability accurately and reasonablely, the results will provide scientific basis for disaster prevention in engineering construction of karst areas.
