浅谈“三背回填”质量控制

Quality Control of "Three Structures′ Back Fill"

"三背回填"是公路工程的重要组成部分,出现错台、沉降、结构物位移等现象,直接影响到公路路基的稳定性,影响车辆行驶的安全度和舒适度,对此,在公路设计、施工和质量检测方面也提出更高的要求。本文从地基处理、填料选择、施工工艺及加筋土运用四方面对施工进行了改进,达到了质量控制要求。

＂Three structures＂ back fill＂ is an important part of highway engineering. The faulting of slab ends, sedimentation, structure displacement and other phenomena directly affect the stability of highway roadbed and the safety and comfort of traffic. For this the higher requirements for highway design, construction and quality inspection are also put forward. The construction was improved from the foundation treatment, selectian of packing material, construction technology and reinforced soil using, and it meets the requirements of quality control.
