针对汉口站存在的深厚层淤泥质粉质黏土、部分夹杂粉砂透镜体的地质情况,结合复杂的周边环境,并按照实际施工需求,制定了排桩加一道钢内支撑、双排桩等支护方案。采用古典法、弹性法等对不同设计剖面及内支撑系统进行了理论计算分析。同时依据有关规范制定了基坑监测方案,对监测结果进行了整理,并与理论计算值对比分析,表明本基坑支护合理可行,可供同类工程借鉴。
According to the geological conditions of deep silty silty clay and some mixed silt lenses existing in Hankou Station and combining with the complicated surrounding environment and according to the actual construction requirements, Protection program. Using classical method and elastic method, theoretical calculation and analysis of different design sections and internal support systems are carried out. At the same time, the foundation pit monitoring program was formulated in accordance with relevant norms, and the monitoring results were collated. Compared with the theoretical calculation, the results show that the foundation pit support is reasonable and feasible and can be used for reference of similar projects.
