| 摘 要： | 通过工程实例,介绍了在对被船只等漂浮物撞击受损的桥墩进行裂缝检测的过程中,运用压水试验计算等价裂缝开度判定桥墩裂缝大小及分布情况的方法.该方法在检测时间紧、桥墩高度大,短时间内无法近距离直接对裂缝进行观测的情况下,不失为一种有效实用的方法,而且可以据此对水下、地面线以下桩基础受损情况作出判断.

| Abstract: | In this article,a method is introduced to do the crack surveying work when the bridge pier was hit by sheep or other floating objects on the water.This method is called pump-in test.The data of the test can be used to calculate the equivalence crack opening,so that the crack width and it's distribute on the pier can be estimated.This engineering example point out that this method is useful when the work must be down in a short time but the pier is too high to do the crack surveying work.This method can be a... |
