预应力混凝土枕枕中截面静载试验方法分析

Analysis on the Static Load Test Method for the Middle Part Section of Prestressed Concrete Sleeper

根据预应力混凝土枕的枕中截面静载试验时轨枕放置方向的不同,以及我国现有轨枕静载试验机加载方式的不同,分析并换算出各种加载方式的实际荷载检验值,从而确保枕中截面静载试验负弯矩检验值的准确与合理。

According to the different placement directions in the static load test of middle part section of prestressed concrete sleeper,and based on the different static loading methods of test machines used in China,the author analyses and calculates the actual load values of different loading methods,so as to ensure the accuracy and rational of the bending moment value in static load test.
