冉渡滩水库工程大坝枢纽区场内交通布置设计
|
摘要
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,遵照施工场内交通布置原则和标准,结合地形、地质及水文等自然条件,分析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 transport layout,based on the transportation layout principles and standards in the jobsite and combined the topography,geology,hydrology and other natural conditions,the technical key of transportation conditions and transportation flow in hub areas has been analyzed,and the transportation planning arrangement schemes such as on-site transportation,cross-river traffic and dam sub-section pouring has been demonstrated. The application shows that after optimized and adjusted the traffic arrangement the construction site is effectively utilized,the layout of the road and bridge facilities is reasonable,it can make the road in multiple use and avoid mutual interference. This scheme with high safe and efficient vehicle traffic can meet the transportation requirements during the peak construction period.
