地铁工程勘察现状与技术研究课题

Present Situation of Subway Engineering Exploration and Technology Research Topics

地铁勘察的特点:一是没有征地的勘察,二是地下系统工程的勘察;我国地铁勘察经历了探索、积累和规范化的历史发展时期,各时期按照可行性研究、初步勘察、详细勘察、施工勘察四个勘察阶段进行工作;根据地铁设计要求和地质条件采取多样化的测试手段,勘察内容全面,技术逐步完善,具有明显的专业特色;今后应结合地铁施工方法和设计要求,研究和总结特殊设计指标的测试技术,解决地铁结构在第四系饱和砂层中的抗震设计问题,加强施工新技术和新方法在不同地质条件下的适应性研究,在安全、快速施工和降低造价等方面不懈努力。

The characteristics of the subway exploration, one is the exploration that not bought the land for construction, the other is the exploration that underground system engineering. The subway exploration of our country experiences the three history development period witch explore,accumulate and standardization, each period carry on works according to four exploration stages that is possibility research exploration,the preliminary exploration, the detailed exploration and implemental exploration. According to the subway design requests and geology circumstance to adopt diversification text instrumentality, exploration contents completely, tech- niques gradually perfect, have obvious specialization features. Aftertime should be combining the construction＇ s methods and design re- quirements of metro, research and concluded the test technology of special design indicators, solve the seismic design problem that subway structure at the fourth-saturated water-filled sand, strengthen research adaptability of new technologies and new methods of construction in different geological conditions, we must work hard in security and speedy construction and cost reduction etc.
