公路月刊1958年4月号发表的“桥头锥坡曲线部份的设置”一文中,介绍了锥坡曲线设置的查表方法。这种方法在一定程度上应用起来很方便,但在许多情况下应用时,还受到很大限制,主要的有以下几个方面: 1.锥坡的几何图形是随着路堤边坡与向河心的坡度而变化的,更主要的是随着锥坡高度的变化而变化。因此,在很多情况下,锥坡高度很少遇到如表上所列的以半公尺或整公尺为单位的数值(见该文表2及表3),
Highway Monthly published in April 1958, “Bridge conical slope curve part of the setting” in a paper, introduced the cone slope curve set look-up method. This method is easy to use to a certain degree of application, but in many cases the application is also greatly restricted, mainly in the following aspects: 1. Cone slope geometry with the embankment slope and the river The gradient of the heart changes, more importantly, as the height of the cone slope changes. Therefore, in many cases, the slope height rarely meets the values listed in the table on the order of one meter or one meter (see Tables 2 and 3 of this document)
