摘　　要：在分析、总结西南岩溶地区挖方工程土石比确定方法的基础上,结合西南某岩溶山区大面积挖方工程,系统地研究了岩溶山区土石比的确定、计算方法以及精度的影响因素,提出了岩溶山区大面积挖方工程确定土石比的方法和工作程序。工程实践证明,按此方法和程序,获得的土石比精度高,可推广使用。Based on analysis and summarization of method determining soil-rock ratio in excavation works in southwest karst mountains,the determination and calculation methods thereof and the factors affecting the accuracy,in relation to the certain large-area works there, were studied systematically, and the specific method and procedure were proposed. Through practice,the method and procedure were proved to achieve high accuracy on soil-rock ratio,and then may be used extensively.
