广深港客运专线深圳福田站为我国第一座大型的客运专线地下车站。为确保车站基坑施工过程中周边建筑物的安全,就基坑施工对周边构筑物的影响进行了深入分析。探讨了硬化模型(HS模型)和莫尔库伦模型(MC模型)土体本构关系对基坑数值模拟的适应性。在考虑风载的不利因素作用下,分析了车站基坑施工对距离基坑只有12 m的香格里拉酒店的影响,为今后工程的设计与施工和周边建筑物的安全控制提供了参考依据。
Guangzhou-Shenzhen-Hong Kong Passenger Line Shenzhen Futian Station is the first large underground passenger station in China. In order to ensure the safety of the surrounding buildings during the construction of the foundation pit of the station, the influence of the construction of the foundation pit on the surrounding structures was deeply analyzed. The adaptability of the soil constitutive relation between the hardening model (HS model) and the Molculun model (MC model) to the numerical simulation of the foundation pit was discussed. Taking into account the unfavorable factors of wind load, this paper analyzes the influence of the pit construction on the Shangri-La hotel, which is only 12 m away from the foundation pit, which provides a reference for the future design and construction of the project and the safety control of the surrounding buildings.
