摘要
中国东部沿海地区广泛分布的海相软土,因其独特的力学特性和地质成因,对城市轨道交通建设产生了重大影响。针对中国五个典型区域的11个城市中的海相软土进行详细分析,旨在深入理解其地质成因、颗粒组成、矿物成分和微观结构特点,并总结其物理力学性质、蠕变性和触变性等关键工程特性。通过典型工程案例分析,揭示了城市轨道交通建设在海相软土地层中遭遇的工程风险,并基于实例分析,提出一系列海相软土地区轨道交通工程设计和施工的指导建议。特别强调有效控制和管理相关风险的策略,包括土体加固、改良技术和智能化监测手段的应用。该研究为理解海相软土的复杂工程行为提供了新的视角,对推进沿海地区城市轨道交通建设的安全与稳定具有重要意义。
Marine soft soil,widely distributed along China's eastern coastal regions,significantly impacts urban rail transit construction.This study focuses on marine soft soils from 11 cities across five typical regions in China,analyzing their geological origins,particle compositions,mineral components,and microstructures.It summarizes the engineering characteristics such as physical and mechanical properties,creep,and thixotropy.Based on typical engineering case analyses,the research addresses the engineering risks encountered in urlian rail transit construction within marine soft soil strata.It offeis guidance for the design and construction of rail transit projects in these areas and suggests effective methods for managing and controlling related risks.
