3)  tunnel support
巷道支护
1.
Application of bolt connecting chain in tunnel support under complex geological conditions;
锚杆联系链在复杂地质条件下巷道支护中的应用
2.
Since the complexity and uncertainty, static design used for underground engineering is inadvisable, so dynamic informative design for tunnel support is introduced.
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。
