浅谈国标《城市轨道交通岩土工程勘察规范》中的风险控制思想

Simple discussion on the risk control thought in the national standard "Code for geotechnical investigations of urban rail transit"

城市轨道交通工程具有结构类型多、施工工法工艺复杂、城市周边环境复杂、跨越地质单元多、城市地质人工扰动大等特点,这些特点使得快速发展的城市轨道交通工程安全风险问题越来越突出。通过对规范的总则、基本规定、施工勘察、工法勘察、不良地质作用、工程周边环境调查、地下水勘察、现场检验与检测等方面的分析研究,论述了新版规范编制中的风险控制思想。

There are many characteristics in the urban rail transit engineering such as the lots of structure types,the complex of the construction method,the complex of urban surrounding environment,the multiples of geological units,the serious artificial disturbance of the urban geology and so on,which make the engineering safety risk problems become more and more serious in the rapid development of urban rail transit.Through the study on the general,basic rules,construction survey,geological prospecting,unfavorable geological action,engineering environment investigation,groundwater prospecting,the field inspection and testing in the national code,the risk control thought in the design of the new standard are discussed.
