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。
Bubble-mixed lightweight soil is a new type of environmentally friendly geotechnical material that has begun to be used as embankment filler. However, the optimal thickness of each floor has still not been solved. Based on the developed instrument that can be used to measure the intensity of bubble mixed light soil along the embankment during the construction period, based on the given test principle and test procedure, and the basis for determining the optimal pouring thickness, Demonstration, proposed bubble mixed light soil embankment packing as the best method to determine the thickness of the pouring. For the field test section of the project, it is recommended that the pouring thickness control within 500 mm. This study not only benefits the quality control of bubble mixed light earth as embankment filler, but also provides technical support for its wider application.
