摘要
预制桩被大量地应用于宁波软土地区,且在工民建项目中有应用越来越多的趋势。结合宁波中心城区工程实例,对比分析根据JGJ 94—2008建筑桩基技术规范双桥静力触探法和经验参数法所估算预制桩单桩竖向极限承载力标准值的差异,并与静载检测成果作对比分析,进而对规范公式进行适当修正,初步得出适用于该工程的经验公式,为宁波地区运用双桥静力触探试验方法准确计算单桩竖向承载力标准值、优化桩基设计方案提供借鉴意义。
Prefabricated piles are widely used in soft soil area of Ningbo,and there is an increasing trend of application in civil and industrial construction projects.In this paper,the difference of the standard value of vertical ultimate bearing capacity of prefabricated pile based on the double bridge static penetration method and empirical parameter method in Technical Code for Building Pile Foundation(JGJ 94—2008)is compared and analyzed with the static load test results,and then the standard formula is modified properly.The empirical formula suitable for this project is preliminarily obtained,which provides reference significance for accurately calculating the standard value of vertical bearing capacity of single pile and optimizing the design scheme of pile foundation in Ningbo area by using the static testing method of double bridge.
