美国me delland 和Fecht对管桩进行了水平荷载試驗並得到很好的效果。本文簡略介紹玉野沼光进行桥墩基础抗震计算研究所取得的一些成果。一、基础地基系数 me delland 和Fecht的試驗所求得的基础地基系数是在买驗室內进行的。所谓基础地基系数是地基給結构物以反力之处,因結构物移动而发生之变位。此基础地基系数K值位于地中深处,不仅垂直方向有此点而且水平方向也有此点。所以基础地基系数K值和決定道路
American medelland and Fecht conducted horizontal load tests on pipe piles and achieved good results. This article briefly introduces some achievements made by Yushino Marsh Light in seismic calculation of bridge pier foundation. First, the basic foundation coefficient me delland and Fecht test found the foundation coefficient is in the laboratory. The so-called basic foundation coefficient is the foundation to the structure of the reaction force, due to the structure of the displacement occurred. This foundation foundation coefficient K value is located in the depths of the earth, not only in the vertical direction but also in the horizontal direction. Therefore, the value of the foundation foundation coefficient K and determine the road
