随着中国城市化进程的加速发展,在城市建设过程中正遇到越来越多的深基坑工程。深基坑向着更大、更深的方向发展,而且大量工程处在市区,场地小、环境要求苛刻,基坑开挖带来的问题也越来越突出。桩撑锚组合支护结构是一种复杂的的组合支护形式,其影响因素众多,目前设计理论尚不成熟。结合工程实例,通过数值模拟和现场监测,分析桩撑锚组合支护结构的受力和变形规律,并对设计和监测提出了一些建议。
With the accelerated development of urbanization in China, more and more deep foundation pit projects are being encountered in urban construction. Deep foundation pit has been developed in larger and deeper direction. Moreover, a large number of engineering offices are located in urban areas with small sites and demanding environmental conditions. Problems caused by excavation of foundation pit are also becoming more and more prominent. Pile-anchor combination support structure is a complex form of combined support, its influencing factors are numerous, the current design theory is not yet mature. Combined with engineering examples, through the numerical simulation and on-site monitoring, the stress and deformation of pile-anchor composite support structure are analyzed, and some suggestions for design and monitoring are put forward.
