深基坑支护工程是一个复杂的系统工程,支护方案的优劣受众多因素影响,本文以某工程基坑支护工程为例,介绍基坑支护工程中的施工工序以及它的控制要点,为规范建筑基坑工程监测工作,保证监测质量,优化设计及指导施工提供可靠依据,通过扩大头锚索在基坑支护工程中的施工工序以及它的控制要点,比较它同普通锚索的联系与区别,分析扩大头锚索的优缺点和它的适用范围、发展前景,是一种处理复杂的多目标决策问题的实用方法。
The deep foundation pit support project is a complex system project. The merits and demerits of the support scheme are affected by many factors. This paper takes the foundation pit support project as an example to introduce the construction process and its control in the foundation pit support project. The key point is to standardize the monitoring of construction foundation pits, ensure monitoring quality, optimize design and guide construction, and provide a reliable basis. By expanding the construction process of the anchor cable in the foundation pit supporting project and its control points, it is compared with the ordinary anchor. The connection and difference between the cable and the analysis of the advantages and disadvantages of the extension of the anchor cable, its scope of application, and its development prospects are practical methods for handling complicated multi-objective decision problems.
