摘要

气泡混合轻质土是一种新型的环保岩土材料，已开始作为路堤填料应用。然而至今每层的最佳填筑厚度问题仍未解决。基于研制的一种可用于测量施工期气泡混合轻质土强度沿路堤深度变化的仪器，在给出相应的测试原理和测试步骤，以及确定最佳浇筑厚度判定依据的基础上，通过工程实例的论证，提出了气泡混合轻质土作为路堤填料时最佳浇筑厚度的确定方法。针对现场试验段的工程情况，建议浇筑厚度控制在500 mm以内。该项研究不仅有利于气泡混合轻质土作为路堤填料的施工质量控制，而且为其更广泛地应用提供技术支撑。

Abstract

Foamed mixture lightweight soil (FMLS) is a new environmental protection geotechnical material. It has been applied to embankment filling. However

the issue of optimum casting thickness of each layer FMLS has not been solved yet until now. In this study

a self-developed instrument is used to measure the strength of the FMLS at different depths during construction. The testing principles and steps are given; and the judgment criterion of the optimum casting thickness is determined. Through an engineering case

a method is proposed for determining the optimum casting thickness for FMLS as embankment filling material. It is suggested that the optimum casting thickness should be controlled within 500 mm for test section. This procedure is beneficial to control construction quality of FMLS as embankment filling material.
