中文摘要:
      以天津市主城区综合管廊建设勘察阶段不良地质环境危险源为出发点,依据查阅的古籍资料、大量钻孔数据归纳分析和原位测试资料,并结合工程经验,分析汇总了工程勘察中人工填土、软土、新近沉积土、古河道、地下水位、地下水腐蚀性、承压水、粉(砂)土液化、地面沉降、活动断裂和岩土参数取值等11种地质因素的危险源。并针对存在的风险因素,提出了相应的建议措施。为天津市主城区的综合管廊建设规避勘察风险,提高建设安全性提供了参考。
英文摘要:
      Comprehensive utility tunnel construction in Tianjin urban area of bad geological environment hazards as the starting point, depending on the data of ancient books, a large number of survey drilling data, in situ test data, and combined with engineering experience, this paper analyzes and summarizes the hazard sources of 11 geological factors in engineering investigation, such as artificial fill, soft soil, recently deposited soil, ancient rivers, underground water level, groundwater corrosivity, confined water, liquefaction of silt soil, ground subsidence, active fault and selection of geotechnical parameters. In view of the existing risk factors, the corresponding measures are proposed. Finally, it provides a reference for avoiding risks and improving construction safety for comprehensive pipe corridor construction in Tianjin urban area.
