【摘要】 土钉支护施工技术,近几年在我国许多大中城市的高层建筑基坑施工中得到推广应用,并对基坑支护工程的设计施工产生了深远的影响。土钉支护结构轻型,柔性大,施工简单方便,施工速度快,经济效益显著,因此发展速度较快。但是,由于场地水文地质条件、基坑周边建筑物和地下管线的复杂性,土钉支护设计施工方法应因地制宜。该施工技术在温州应用以来,先后完成了松台1-2#地块、华侨饭店二期工程、解放南路15#地块、信河街6#地块、方正地块等数项工程,取得了较好的社会效益以及经济效益。本文旨在通过对温州旧城区基坑支护设计施工实践的总结,针对温州地区地下水丰富、土质软弱的这一实际情况,对土钉支护设计施工技术在温州旧城区的应用进行讨论。本文主要做了以下一些工作:①分析总结土钉支护技术的国内外发展状况和技术特点。②分析土钉支护技术的工作机理、性能、优点与局限性。③研究土钉支护技术的设计与施工。④研究土钉支护技术的现场试验与监测。⑤结合具体工程进一步探讨土钉支护技术的设计与施工。更多还原

【Abstract】 The soil nailing technique to the excavation of the top construction have been applied in nearly several years in many large and middle cities and the opened cities along the coast in our countries, it has an deep and long effect on design and building of the excavation. The soil nailing technique develops quickly because of its light structure, fexibility, as well as easy and fast and obvious economic effect. But the design and building of soil nailing must adapt the working method to local conditions, it is complex in the conditions of hydrology and geology at an area of level ground, characteristic of construction near the vacation and piping’s in the underground. Since the building technique is applied in Wenzhou, several projects have been completed such as Song Tai1-2# district, the second project of Overseas Chinese Hotel, the fifteenth district at Jie Fang Nan road,the sixth district at theXin He road ,Fang Zheng district and so on. This techniques have led to the good economical and social efficacy.Directing towards the soft soil and the rich under-ground water, this paper discusses the application about the technique of the soil nailing design and building in Wenzhou’s old city district by slumping the practices.The work include the following items:①summary and analysis of the character and the development of soiling nailing techinique home and abroad.②Analysis of the constitution, merits and faults of the soil nailing technique were③Study of the design and construction of the soil nailing technique④Site test and monitor on the soil nailing technique⑤Based on specific engineering, the special problems in the engineering and the settle methods were introduced.更多还原
