机械扩大头锚索在成都膨胀土地区深基坑支护中的应用
摘要:在膨胀土地区进行基坑支护设计时，常规的桩锚支护体系受到很大限制。以成都膨胀土地区某深基坑支护工程为例，根据本工程特点，综合考虑安全、经济、效率、环保等因素，确定采用机械扩大头锚索+排桩型式进行支护，并对方案选型、施工关键技术、现场试验等过程进行了详细的介绍，通过监测结果的验证，阐明该扩大头锚索支挡结构体系能够很好地适应膨胀土的特殊地质条件及复杂的周边环境，具有极好的推广价值，为今后类似工程的建设提供一定的参考和借鉴。
Abstract:In the design of foundation pit support in expansive soil area, the conventional pile anchor support system is greatly limited. This paper takes a deep foundation pit supporting project in expansive soil area of Chengdu as an example,according to the characteristics of this project, considering safety, economy, efficiency, environmental protection and other factors, the mechanical expansion anchor pulling pile retaining structure is finally determined, and the scheme selection, support parameter, calculation and analysis process is described in detail.Finally, the monitoring results of the verification, the new retaining structure can adapt to the special geological conditions of expansive soil good and complex surrounding environment, has excellent popularization value and provide some reference for the construction of similar projects in the future.
