摘要
快速维持荷载法是《建筑基桩检测技术规范》(JGJ106-2014)中规定的两种单桩竖向抗压静载试验方法之一。快速法试验周期短,可以减少昼夜温差等环境影响引起的沉降观测误差,是验收检测中较常用的试验方法。但快速法使用有一定限制条件,《建筑基桩检测技术规范》(JGJ106-2014)中要求有成熟地区经验时方可使用。本文针对大连地区岩溶区域的桩基进行了快速法和慢速法的对比试验研究,提出了在岩溶地区使用快速维持荷载法的建议,对类似区域的桩基静载试验有一定的参考价值。
Quick load maintain law is“building pile foundation detection technology specification”(JGJ106-2014)of the provisions of the two kinds of single pile vertical compressive static load test method. The rapid test cycle is short,can reduce the settlement observation error caused by the temperature difference between day and night environmental impact test method, is more commonly used in the acceptance test. But the rapid method used has some restrictions“,technical code for testing of building foundation piles”(JGJ106-2014)can be used in requires a mature area of experience. The contrast experimental study on fast and slow method for pile foundation in karst area of Dalian area,proposed the use of quick load maintain law in karst regions,have certain reference value for the similar region of the static load test of pile foundation.
