桩基础在桥梁施工中占据着重要的位置。由于桥梁桩基施工的隐蔽性,在施工过程中存在不可预见性的因素较多,如果这些问题不及时解决,将直接影响到桩基的工程质量。桩基质量检测技术涉及到力学、振动学、桩基施工技术和计算机技术等诸多学科知识,它既不同于常规的建筑材料试验,又不同于普通的建筑结构测试,从检测技术来看,主要是对桩基和周围地质的检测,检测方法、频率也不断加强,目前常用的有静荷载试验、高应变、低应变、声波透射法、钻孔取芯法等方法。
Pile foundation occupies an important position in the bridge construction. Due to the hidden nature of the construction of bridge pile foundation, there are many unforeseeable factors in the construction process. If these problems are not solved in time, it will directly affect the project quality of pile foundation. Pile foundation quality testing technology involves a lot of disciplines such as mechanics, vibration, pile construction technology and computer technology, which is different from the conventional building materials testing, but also different from the ordinary building structure testing, from the detection technology, the main Is the pile foundation and the surrounding geological testing, testing methods, the frequency has also been strengthened, the commonly used static load test, high strain, low strain, acoustic transmission method, drilling coring method.
