随着我国经济的不断迅猛发展,我国运输行业也在飞速发展,这使得我国的公路建设也得到了十足的发展,特别是我国的高速公路建设,在近些年更是呈现出几何方式的增长,并且随着我国西部大开发的发展方针以及逐步向中国梦靠近,我国高速公路的发展侧重点也逐渐由我国东部沿海地区向中西部地区转移,但是我国中西部地区山区较多,这就造成了我国中西部地区地形多变、地质构造复杂的状况。这就导致了在建设高速公路的时候容易出现路基沉降的情况,一旦出现路基沉降范围过大,就会使路面构造裂开出现错台等现象,这种情况的出现将会直接影响路面的使用寿命。对于高速公路来讲,路基有着极为重要的作用,所以路基的沉降是工程建设中的需要解决的主要问题。作者根据自什么多年的工作经验对路基沉降的控制进行了简要的介绍。
With the continuous rapid economic development in our country, the transportation industry in our country is also developing rapidly, which makes the highway construction of our country get a full development too. Especially the expressway construction in our country has shown a geometric increase in recent years , And along with the development policy of our country’s western development and its close proximity to the Chinese dream, the focus of the development of our country’s expressway has gradually shifted from the eastern coastal areas of China to the central and western regions, but there are more mountainous areas in the central and western regions of our country, resulting in China’s central and western regions of the terrain change, complex geological structure. This leads to the situation of subsidence easily occurring in the construction of expressways. Once the settlement of subgrade is too large, the structure of the pavement will be split to appear the wrong platform. The appearance of such situation will directly affect the use of pavement life. For expressways, the subgrade plays an extremely important role. Therefore, the settlement of roadbed is the main problem that needs to be solved in engineering construction. The author gives a brief introduction of the control of subgrade settlement based on years of working experience.
