摘要
在地下工程施工中,根据围岩稳定性分类确定围岩开挖和支护施工措施及参数是行之有效的手段,在水电工程领域,取得了根据工程地质力学参数进行围岩分类的成果,但在应用中存在不足.经研究并结合原有成果,建立围岩稳定性模糊综合评价模型可弥补其不足,使原有成果的运用更方便可靠。实践证明,该模型是合理可行的。
In the construction of underground projects,the parameters and measures of excavation and supporting are usually determined by the stability class of the surrounding rocks.In the construction area of water and hydro-electric projects,the research result was gained for surrounding rock stability classification according to the geologic and mechanical parameters.But there are some shortcomings in using it.After researching,a Fuzzy synthetic evaluation model is established.Testified by the practice,the model can make up for the shortcomings and make it easy and reasonable to use the old result.
