%X 公路工程中，沥青路面的结构形式很多，本文针对半刚性基层、级配碎石基层、倒装结构以及全厚式沥青路面这几种典型的结构形式，总结了国内外工程中部分典型的结构组合，并分析了各自的优缺点、适用性以及受力特性。然后本文基于我国长寿命沥青路面的发展需要，基于有限元的方法，着重分析了倒装结构层的受力特点，总结了各层模量和厚度变化对力学计算指标的影响规律。最后提出了对我国长寿命沥青路面的思考，指出了我国倒装结构在理论上有实现长寿命的潜能和优势，但还需要大量工程实践的摸索和证明。<br />
There are many structural forms of asphalt pavement in road engineering. Aiming at several typical structural forms of semi-rigid base, graded crushed stone base, inverted structure and full- thickness asphalt pavement, this paper summarizes some typical structural combinations in domestic and foreign projects, and analyzes their advantages and disadvantages, applicability and stress characteristics. Then, based on the demand of long-life asphalt pavement in China, this paper focuses on the stress characteristics of inverted structure by using the finite element method, and summarizes the influence law of the change of modulus and thickness of each layer on the mechanical indexes. Finally, it makes a discussion on the long-life asphalt pavement in China, and points out that the inverted structure in China has the potential and advantages to realize long-life in theory, but it still needs a lot of exploration and proof of practice.
