【摘要】：我国上世纪90年代建好的高速公路，在持续快速增长的交通量下，，公路服务水平明显降低，已经不能适应社会经济快速发展的需要。目前，全国范围内越来越多的高速公路都进入了改扩建阶段。由于高速公路改扩建期间施工路段的拥堵、交通事故频发等严重影响道路安全运行。因此，开展对高速公路改扩建工程交通组织和施工作业区布置的研究显得十分迫切。本文以杭金衢高速公路义乌至金华段改扩建工程为依托，讨论了高速公路改扩建交通组织的设计原则以及分流原则和方案，分别为安全原则、边通车边施工原则、畅通原则、确保施工进度原则、效益最佳原则；对于特殊工点，主要是一般单喇叭互通立交施工路段，上溪互通施工路段，金华枢纽改造，人行（机耕）天桥拆除原位重建或移位重建交通组织路段和桥梁换板施工等所采取的有针对性的交通组织设计；对改扩建施工作业区设施的设置进行了规定，明确了作业安全标志的摆放与拆除的要点与要求。
[Abstract]:In -10s, the highway built in China, under the sustained rapid growth of traffic volume, the level of highway service has been significantly reduced, has been unable to meet the needs of the rapid development of social economy. More and more expressways throughout the country have entered the stage of reconstruction and extension. Due to the congestion of construction sections during the period of highway reconstruction and extension, frequent traffic accidents and other serious impact on road safety operation. It is urgent to carry out research on traffic organization and operation area layout of expressway reconstruction and extension project. Based on the reconstruction and extension project between Yiwu and Jinhua section of Hangjin-qu expressway, this paper discusses the design principle, shunt principle and scheme of highway reconstruction and expansion, which are respectively safety principles. The principle of construction while opening to traffic, the principle of smooth flow, the principle of ensuring construction schedule and the principle of optimal benefit; For special work points, it is mainly the construction section of the general single horn interchange, the construction section of Shangxi interworking, and the reconstruction of Jinhua hub. The targeted traffic organization design adopted by the people's Bank of China (machine ploughing) flyover demolition in situ reconstruction or displacement reconstruction of traffic organization section and bridge plate replacement construction etc.; The installation of the facilities in the operation area for reconstruction and extension is stipulated, and the key points and requirements for the placement and demolition of the work safety signs are made clear.
