冉渡滩水库工程大坝枢纽区场内交通布置设计

Traffic Layout Design in Dam Hub Area of Randutan Reservoir Project

针对冉渡滩水库工程两岸地形陡峭、施工场地与河床高差较大,河床交通布置条件较差等问题。以施工场内交通布置原则和标准为准,结合地形、地质及水文等自然条件,分析了枢纽区交通条件及运输流向等技术关键,重点对场内交通、跨河交通和大坝分部位浇筑等交通规划布置方案进行了论证。工程实践表明:经优化调整后的交通布置方案,施工场地得到有效利用,道桥设施布局合理,做到一路多用,并避免相互干扰,能够满足施工高峰期运输要求,车辆通行安全高效。

Aiming at the problems of steep terrain on both river banks, large altitude difference between jobsite and riverbed, poor conditions for traffic layout, Based on the principles and standards of traffic layout in construction site, combined with natural conditions such as topography, geology and hydrology, the paper analyses the key technologies of traffic conditions and transportation direction in the hub area, and mainly demonstrates the traffic planning and layout schemes such as intra-site traffic, river-crossing traffic and dam partial pouring. The practice shows that the optimized and adjusted traffic arrangement scheme can effectively utilize the construction site, rationalize the layout of road and bridge facilities, achieve multi-purpose along the road, and avoid mutual interference, meet the transportation requirements during the construction peak period, and ensure the safety and efficiency of vehicle traffic.
