Abstract : in compliance with the theories of structural mechanics , and in consideration of all factors that may influence vehicle impact , two new concepts , i . e . road condition factor and amplification factor of impact dynamics are proposed 文摘:從結(jié)構(gòu)力學(xué)的理論出發(fā),考慮影響車輛沖擊力的各種因素,提出了路況系數(shù)和沖擊動力放大系數(shù)兩個新概念;克服了目前簡單確定沖擊系數(shù)和直線中插確定沖擊力的弊端。
5 the effect of complex media protruding topography on seismic wave propagation the protruding topography has amplification effect on ground motion while the hillside has constraint effect . the amplification factor of the valley bewteen two moutains is related to the distance of the two moutains 5 、復(fù)雜介質(zhì)凸起地形對地展波傳播的影響山體對地面運動有放大作用,在山腳則有抑制作用,山包之間峽谷的土層反應(yīng)放大倍數(shù)受山包之間距離的影響較大。
The unsaturated soil ( sr = 98 % ) make the topography effect more noticeable than that of saturated soil and one - phase soil : in the amplification area the amplification factor is bigger than that of saturated soil and one - pahse soil , while in the constraint area the amplification factor is smaller than that of saturated soil and one - phase soil 介質(zhì)的種類對地形放大倍數(shù)有比較明顯的影響。欠飽和土比單相土具有更明顯的地形效應(yīng),在被抑制區(qū)欠飽和土的位移或加速度放大倍數(shù)比單相土更小,在放大區(qū)位移或加速度的放大倍數(shù)比單相土更大。
