PHC管桩由于桩质量保证、施工速度快、效率高等优点,在软土地区采用静压法施工已非常广泛,但桩尖的使用各不相同,造价也悬殊较大,本文通过扬州大学新校区建筑面积12万m2桩基工程施工实践和分析,采用简易桩尖取得了良好的经济效益和质量工期保证。1工程概况根据地质勘探结果,我校新校区场地土为软弱土和液化土层,场地类别为三类,对建筑抗震不利。基础
Because of the pile quality assurance, the construction speed and the high efficiency, the PHC pipe pile is widely used in the soft soil area due to the static pressure method. However, the use of the pile tip is different and the cost is also greatly disproportionated. This paper, through the new campus of Yangzhou University Construction area of 120,000 m2 pile foundation construction practice and analysis, the use of simple pile tip has made good economic benefits and quality assurance period. 1 Project Overview According to the results of geological exploration, the site of the new campus of our school is soft soil and liquefied soil. There are three types of venues, which are unfavorable to earthquake proofing of buildings. basis
