Problems Existing in the Development of Road and Bridge Construction in China

作者: Release Date: 2017-09-21 Author: Click:

(I) The design concept of road and bridge construction projects is not good, and the practicality of road and bridge is difficult to be continued

There is no doubt that design work is the core of road and bridge engineering construction. The quality of design work directly determines the level of engineering quality, practicability, engineering cost, ease of construction, and construction period of a road and bridge construction. For a long time, the design concept of road and bridge construction is not good, and the practicality of road and bridge is difficult to be continued. First, the time for road and bridge engineering design work is short, and there is a lack of sufficient safety and economic arguments. Lack of protection of the ecological environment; many bridges are designed with only the current use needs in mind, while neglecting the development of future transportation tools, which makes it difficult to continue practicality. Taking bridge decks as an example, the width of many bridges is not sufficient. Intensifying the situation of urban road congestion; secondly, the lack of use of new materials and technologies in the design of roads and bridges is, on the one hand, due to the consideration of the construction period, and on the other hand, due to the consideration of the cost of technology use. Scientifically, the design of road bridges should focus on the safety, reliability and practicality of road bridges, and should not focus too much on low quality. In particular, the design demonstration period of road and bridge engineering in China and the construction period of road and bridge engineering projects are relatively short. Due to many factors such as technology, cost, and time, China's road and bridge construction design links often only pursue The breakthrough of a single technical indicator and the lack of overall innovative thinking on the road and bridge construction process have ultimately resulted in the poor economic practicality of road and bridge projects in China, and often cause rework, repair or even because of unreasonable design. Reconstruction has caused unnecessary waste and hidden safety hazards in road and bridge construction.

(2) The level of road and bridge construction management is low, and the safety of road and bridge is difficult to be guaranteed

For a long time, the low level of road and bridge construction management is a key problem that plagues the development of road and bridge construction in China, which poses a huge threat to the safe use of road and bridge in China. In recent years, major bridge safety accidents have occurred in China in succession. From July 11 to July 15, 2011, three large bridges collapsed. They were: the collapse of the 328 provincial highway Tongyuhe Bridge in Yancheng, Jiangsu (use The time is less than 15 years), the Wuyishan Mansion Cable-stayed Bridge in Nanping City, Fujian has suddenly broken and collapsed (less than 12 years of use time), and the Hangzhou Qianjiang Third Bridge has suffered a bridge deck accident (less than 14 years of use time). The level of bridge construction and construction management is low, and the safety of road bridges is difficult to be guaranteed. From a practical perspective, the low level of construction management in China ’s road and bridge construction and development is mainly reflected in the following three aspects: First, in the preparation environment for road and bridge construction, China ’s road and bridge construction projects have a relatively large material management aspect. Negligence, confusion in the management of construction materials, and ultimately make road and bridge construction projects unable to achieve optimal allocation of resources. Second, in the implementation phase of road and bridge construction, the level of progress control of road and bridge construction projects is low, and it is often difficult to complete work tasks on time This has a great impact on road and bridge construction. Third, the construction quality supervision of current road and bridge construction projects in China is not strong, the technology of construction quality supervision is immature, and road and bridge construction materials are lagging. The construction of roads and bridges has been carried out in a process of cutting corners and cutting materials, which has seriously affected the use and safety of road and bridge facilities.
