桥台护锥坡脚线可随地形的变化放在稳定的山坡上,以减少土石方和护砌工作量。在山区一般多采用拔台式,见图1(a)。亦可放在临河、临路的斜截式挡墙顶上,截止护锥伸入河道和道路,见图1(b)。本文将论述用双圆图解法求坡脚线的方法。 Bridge abutment Cone slope foot line with the terrain changes on a stable hillside to reduce the earthwork and retaining work load. More commonly used in the mountain pull table, see Figure 1 (a). Can also be placed in the Linhe, temporary road diagonal cut-off wall at the top, cut-off cone into the river and roads, see Figure 1 (b). This article will discuss the method of finding the foot-line with double-circle graphic method.
