一、前言在公路工程中,重力式挡土墙的应用还是常见的。从设计经验知道,对于这类建筑物,主要问题在于抗滑稳定验算,其中关键也就是基底摩擦系数的取值,其值每变动0.1,挡土墙的体积则变动20%左右。尽管它在设计中关系重大,可是实际工程大多数并未作基底摩擦试验,其客观原因就是现场试验费力费时不易做。由于对这方面的研究
First, the preface In highway engineering, the application of gravity retaining wall is still common. From the design experience, we know that for such structures, the main problem lies in the stability calculation of anti-skidding. The key factor is the value of the friction coefficient of the substrate. The value of the retaining wall changes about 20% for every 0.1 of its change. Although it is of great importance in the design, most of the actual projects have not been subjected to the substrate friction test. The objective reason for this is that on-site tests are laborious and time-consuming and difficult to do. Due to the research in this area
