煤矿巷道支护动态信息设计法

由于地下工程环境的复杂性和不确定性,采用的静态信息设计方法存在着明显的缺陷。因此,提出巷道支护动态信息设计法,其实施过程为:在地质调查和地质力学测试的基础上,采用数值模拟和工程类比相结合的方法进行初始设计;将初始设计实施于井下,并进行地质资料的现场再收集和工程监测;用监测结果检验和修正初始设计,按修正后的设计进行施工,并进行工程监测,如此不断循环,直至完工。该方法在煤炭行业获得成功,在金属矿山、交通、水利等岩土工程中有重要的推广价值。

Dynamic Informative Design for Tunnel Support in Coal Mine

Since the complexity and uncertainty, static design used for underground engineering is inadvisable, so dynamic infomative design for tunnel support is introduced. In the course of implementation , the primary design is acccrnplished by numerical simulation combined with engineer analogy based on geological survey and geological mechanics test, which is implemented in the underground pit. During the construction course according to primary design, onsite geolcgical and engineering data are recollected and fed back for revision of the design. The revised design is used as the blueprint for construction .This revision process is repeated again and again fill to the end of construction . This method has been successfully used in coal mines, and might be useful in metal mines, traffic tunnel and hydraulic engineering projects.
