钢筋混凝土预制方桩在新疆阿拉尔地区的工程应用

新疆阿拉尔地处塔克拉玛干大沙漠的北缘,紧邻塔里木河,场地以粉土、粉砂土为主。该地区以往工程建设项目,其地基处理方式以复合地基为主,很少采用桩基,更没有在工程建设中采用过钢筋混凝土预制桩。近年来越来越多具有荷载大、对沉降敏感的项目在该地区实施,仅仅采用复合地基的处理方式已不能完全满足工程建设要求,而需要采用桩基。本文根据阿拉尔钢铁项目钢筋混凝土预制桩的试桩数据,介绍了钢筋混凝土预制方桩在阿拉尔地区钢铁项目建设中的应用情况。

Application of Prefabricated Square Pile of Reinforced Concrete in Project of Alar Region of Xinjiang

Alar of Xinjiang is located in the northern edge of the Taklimakan Desert,it closes to the Tarim River,and its site takes silt,silt sand as main part.Foundation treatment way of engineering construction projects in the region in the past was based on the composite foundation,rarely used pile foundation,let alone used prefabricated reinforced concrete pile in the engineering construction.In recent years,more and more projects of large load and sensitivity to sedimentation have been implemented in the region,only using composite foundation can not fully meet the requirements of engineering construction,which should use pile foundation.According to the pile test data of Alar steel project reinforced precast concrete piles,this paper introduces the application of prefabricated reinforced concrete square pile in steel project construction of Alar region.
