摘　　要：以四川西部的折多山、海子山冰碛层上的重大工程为例,系统地研究了冰碛层土石比的定义和确定方法。结果表明:冰碛层土石比不应机械地按照相关规范确定,而宜按工程类型、规模和施工水平确定;大型土石方工程土石比应按照勘察阶段初步确定,试验段校核,施工调整、修正的程序,采用综合方法确定。Taking the major projects on drift beds of Zheduo Mountain and Haizi Mountain in the west of Sichuan as example, the method defining and determining soil-rock ration of drift beds were studied systematically. The result shows that this ratio shall not be defined according to the related specification by rote, but confirmed as per type, scale and construction level of project ; for large-scale earth and stone work, it shall be identified initially in survey stage, checked in test stage, adjusted and corrected in construction and, finally, determined by integrated approach.
