《道碴桥面鋼筋混凝土梁預应力鋼筋混凝土梁圆形桥墩地震区检算及水流冲击力检算算例》(叁桥4017)是第三設計院編制的全路参考資料。系根据标准图叁桥4016圓端形桥墩中的有关外力及寸尺等进行編制。提出对設計桥墩考虑水流冲击力或地震慣性力检算方法的初步意見,供設計者参考。算例中包括两部份: 1. 圓端形桥墩水流冲击力检算算例按桥規§65条規定进行計算。算例中考虑为Ⅰ級干綫,活载为中-22級,綫路位于平坡曲綫R=600m,曲綫外側在河流下游方向,并列有水文、地质情况及桥孔式样和主要尺寸等数据和資料。对检算方法及步驟作了詳細叙述。 2. 地震区圓端形桥墩检算算例
“Ballast Deck Reinforced Concrete Beam Prestressed RC Beam Circular Bridge Pier Check and Water Impact Check Calculation Example” (Sanqiao 4017) is the Third Design Institute prepared the entire road reference materials. Based on the standard figure Sanqiao 4016 round-end piers in the external forces and related dimensions and other preparation. The preliminary suggestion on the method of calculating impact force or seismic inertia for the design of piers is proposed for designers’ reference. The example includes two parts: 1. The calculation example of circular impact of circular pier is calculated according to the regulations of bridge regulation §65. In the example, the grade Ⅰ trunk line is considered. The live load is at level -22. The line is located at the level slope R = 600m. The outside of the curve is in the downstream of the river. Hydrology and geology, bridge pattern and main dimension data and data . The method of checking and the steps are described in detail. Earthquake area round-shaped piers count calculation example
