载体桩技术的应用及经济性研究

Research and Analysis on Technology and Economy of Engineering Case Applying Piles with Ram-compacted Bearing Sphere

本文首先介绍了载体桩增强机理,然后以洛阳某高中项目为例,结合地质情况,对比分析载体桩、预应力管桩、灌注桩三种桩型技术方案,确定相应单桩承载力特征值,同时,在相同条件下,测算出三种桩型对应的桩数和承台大小,并对其经济性进行对比分析。

This paper first introduced the reinforcement mechanism of carrier pile,and then took a high school proj⁃ect in Luoyang as an example,combining with the geological conditions,compared and analyzed the technical schemes of carrier pile,prestressed pipe pile and cast-in-place pile,and determines the corresponding characteristic value of single pile bearing capacity.At the same time,under the same conditions,the corresponding pile number and bearing platform size of three pile types were measured and calculated,and the economy of three kinds of piles was compared.
