【摘要】 结合不同线形的高速公路道路情况,采用几何运算方法,得出影响防眩效果的植株间距和植株高度的相关公式。其中,直线路段的植株间距公式为:L=2b*[1+〔L1/(B1+B2)2〕]1/2(b表示植株的正投影半径;L表示植株间距;B1、B2表示车辆纵向中线至中央分隔带纵向中线的距离;L1表示两辆车纵向距离);平曲线路段植株间距公式为L=2(bR)1/2(R表示中央分隔带中心线圆弧的半径);平直线路段植株高度公式为H=h1+(h-h1)B1/B或H=h2-(h2-h1)B2/B(h1表示车辆前照灯的高度,h2表示驾驶员视线高度,H表示中央分隔带植株的高度);凹形竖曲线路段植株高度的公式为H=(h1+h2)/2。更多还原

【Abstract】 The space between plants and plant height for mid compartition strip of all kinds of line-forms expressway were studied for the aim of preventing dizzy.The formula of space between plants of a linear highway:L=2b*[1+(L1/(B1+B2))2]1/2;the formula of space between plants of an even curvilinear highway: L=2(bR)1/2;the formula of plant height of a linear highway: H=h1+(h-h1)B1/B or H=h2-(h2-h1)B2/B;and the formula of plant height of a concave erect curve highway: H=(h1+h2)/2.更多还原
