摘要
某拟建铁路地质背景独特,工程地质及水文地质条件复杂,需查明主要工程地质问题,开展基于减灾理念的综合选线研究,针对地质问题采取工程措施规避灾害风险。研究表明:清渔河间地块岩溶与岩溶水系统、环境水文条件、卸荷式地质灾害、页岩气生成与存储等多种地质问题控制铁路通行方案的选择;经专项研究将清渔河间地块岩溶系统细分为5个大区、21个小区,开展人口分布与可利用水资源分级分析,卸荷式地质灾害和页岩气发育规律及影响评价;多方案综合比选,找出可通行方案,提出结合施工组织、环境水文生态保障、工程施工运营风险等多因素统筹考虑的方案研究建议。
The geological background of a proposed railway is unique and the engineering geology and hydrogeology conditions are complex.It is necessary to identify the main engineering geological problems,carry out comprehensive research on route selection based on the concept of disaster reduction,and take engineering measures to avoid disaster risks.The results show that karst and karst water system,environmental hydrological conditions,unloading geological hazards,shale gas generation and storage in Qingyu Hejian block control the selection of railway passage schemes.The karst system of Qingyu Hejian block was subdivided into 5 big areas and 21 small areas by special research.The population distribution and available water resources were classified and the unloading geological hazards and shale gas development laws and their impact were evaluated.Through comprehensive comparison and selection of multiple schemes,the passable schemes are found out,and the scheme research suggestions are put forward considering the construction organization,environment,hydrology and ecological guarantee,engineering construction operation risk and other factors.
