随着公路建设的发展,桥梁的规模、跨度、荷载等级逐渐加大,灌注桩基础以其较高的承载力已经普遍应用于桥梁建设中。而灌注桩由于埋深大属隐蔽工程,且施工工艺流程复杂,是造成桥梁质量问题的关健环节之一。因此,为了保证灌注桩的工程质量,必须从勘察设计直到施工每一过程都严格控制,认真分析处理可能存在的隐患,从而保证桥梁质量。勘察设计问题设计工作必须严格按照勘察报告提供的地层情况及岩土参数进行工作,既 With the development of highway construction, the scale, span and load level of the bridge gradually increase. The pile foundation with its higher bearing capacity has been widely used in the bridge construction. The bored piles, as a result of the deep buried large-scale engineering, and the complicated construction process, are one of the key links in the bridge quality problems. Therefore, in order to ensure the quality of the piles, it is necessary to strictly control every process from survey and design to construction, carefully analyze and deal with possible hidden dangers, so as to ensure bridge quality. Survey and design issues must be designed in strict accordance with the survey report provided by the formation and geotechnical parameters of work, both
