摘要

为解决高液限土路基填筑中弯沉难控制的问题，根据刚度补偿理论和弯沉等效原则，以弯沉为控制目标，提出高液限土路基弯沉控制方法。该方法以下路堤回弹模量、路基各层顶面回弹模量和填筑厚度为计算参数，通过理论计算得到各层填料所需的材料模量，结合室内试验结果选择合适的填料，确定路基弯沉控制的填筑方案，并可根据路基现场施工效果动态调整。以海南省内国道G360公路为依托工程，依据该方法制订方案，铺筑试验路，并进行现场试验验证。结果表明，路基顶面弯沉满足验收要求，且与验收值误差较小。该方法可有效控制路基弯沉，指导高液限土路基施工与质量控制。

Abstract

In order to solve the problem that it is difficult to control the deflection in high liquid limit soil subgrade filling

according to the stiffness compensation theory and deflection equivalent principle

taking the deflection as the control objective

the deflection control method is proposed. In this method

the resilient modulus of lower embankment

the resilient modulus of each layer top surface in subgrade and the filling thickness were taken as the calculation parameters. The material modulus required for fillers in each layer was obtained by theoretical calculation

and the appropriate filler was selected according to laboratory test results. The filling scheme of subgrade deflection control can be determined

and it can be dynamically adjusted according to subgrade construction effect. Taking Hainan National Highway G360 as case history

the test road was paved according to the proposed method

and the field test was carried out. The results show that the subgrade top deflection meets the acceptance requirements and the discrepancy is marginal. This method can effectively control the subgrade deflection

and guide the construction and quality control of high liquid limit soil subgrade.
