狭窄场地条件下基坑的土钉支护技术

Soil nailing supporting technique for foundation pit on narrow construction site

根据津巴布韦人力资源发展基金会综合楼工程实例，说明了土钉支护的设计、验算、施工和监测．工程实践表明，在地下水位较低、土层条件较好，但场地狭窄的情况下应用土钉支护技术，施工方法简便，施工周期短、成本低，能有效保证边坡稳定．

In the light of construction practice of the complex of Zimbabwe Manpower Development Fund, the design, checking calculation, construction, and monitoring of the soil mailing support are described. The project practice shows that, when under ground water level is low and soil condition is more favorable, application of this technique to the excavation of foundation pit on narrow construction site can make the construction procedure simple, construction period short, and construction cost low as well as can effectively guarantee the pit side to be stable.
