摘要
桥梁工程的大直径桩采用钻孔灌注桩,钻孔灌注桩施工完毕,根据《建筑桩基技术规范》(JGJ94-1994)和《公路桥涵地基与基础设计规范》(JTJ 024-1985)的要求,采取动测试验、静载荷试验、钻探取芯3种联合试验对桩身及桩基础的质量进行检测,并结合现场的施工记录资料,综合分析产生桩基工程质量事故原因,对桥梁桩基础的安全进行评价,并积极采取可行措施进行加固处理。
The pile of bridge engineering is constructed with bored in-situ pile, according to the demand of Technical Code for Building Pile Foundation （ JGJ94-94 ） and Specifications for Design of Ground Base and Foundation of Highway Bridges and Culverts （JTJ 024-85 ） , the engineering pile must be detected . The results of pile static load test , dynamic test and pile sample dug test show the insufficiency of pile vertical bearing capacity and the defect problem. Based on those tests results, geological condition and construction material , re-medical measures were adopted after comprehensively analyzing the accident causes. The quality safety of bored in-situ pile is evaluated, and some treatment methods were constructed actively.
