前言察布查尔县大稻渠的乔库尔大桥设计,坚持实用、安全、美观,经济的设计原则。对此桥作了多种设计方案的比较。原设计为单跨12米共4跨的双曲拱桥,概算总投资为21.7万元。由于大稻渠断面宽浅,建双曲拱桥工程量大,总投资亦偏大。尔后提出五跨钢筋混凝土简支梁设计方案,但因此方案桥孔多,地下水位高,有6个墩台基础,开挖十分困难。最后又提出三跨钢筋混凝土连续梁设计方案。(参看图1),概算总投资13.4

Preface Qiaoqur Bridge in Dakotuqu, Qapqar County, insists on the design principles of practicality, safety, beauty and economy. This bridge made a variety of design comparison. The original design for a single span of 12 meters a total of 4 double-curved arch bridge, the estimated total investment of 21.7 million. Due to the shallow section of Daoqu River, the construction of double-curved arch bridge is large in quantity and the total investment is also large. Later proposed five-span reinforced concrete simply supported beam design, but the program more bridge holes, groundwater level is high, there are 6 piers and foundations, excavation is very difficult. Finally, a three-span RC continuous beam design scheme is proposed. (See Figure 1), the estimated total investment of 13.4
