In this paper, author compare with shenzhen holiday plaza project ( be known as firstly deepest foundation pit, deepest excavation depth is 21m ), use combinative method for theory guidance, test study, simulation analysis, project application and information feedback, entirely and deeply study prestress anchor cable composite soil nail, and also make a pilot study for deformation of pile anchor composite soil nail
本文以深圳假日廣場深基坑支護工程（號稱「深圳第一坑」 ，最深開挖21m ）為背景，採用了理論指導、試驗研究、模擬分析、工程應用和信息反饋相結合的方法，對預應力錨索復合土釘支護結構進行了全面深入的研究，對樁錨式復合土釘支護結構的變形進行了初步研究。 -
Construction of flat tunnel of large span at extra - shallow depth must be conducted on the principle that advance grouting should be strictly performed before excavation and length of pull at one time should be short, together with reinforced support, immediate closing and constant monitoring and surveying. that preceding pilot tunnels, large - volume excavation divided into small ones, excavation of flank before that of center, upper before lower, arch before wall etc is a good method which could effectively reduce surface subsidence and its adverse effect on adjacent buildings, in addition, some other measures are also taken to lessen blast - induced vibration in the ground and surrounding structures. in a word, all means and steps mentioned above have already proved effective and practicable in practice
軟弱大跨超淺埋扁平隧道必須按「管超前，嚴注漿，多分部、短開挖、強支護、快封閉，勤量測」的施工原則進行施工，採用「眼鏡超前，化大為小，先側后中，先上後下，先拱后墻」的施工方法控制地表沉降和對周邊建築物的影響；採用「多分部，化大為小，短進尺，密布眼，弱裝藥，設減振槽」 ，控制爆破振動，經過實踐證明，這些方法都是行之有效的。
