摘要
随着我国GDP总量不断增长,中西部地区的基础设施亟待完善,而西部地区机场建设发展非常迅速,但大多机场建设在较为偏僻的地方,且中西部地区存在大量的湿陷性黄土,机场建设面临着一系列特殊问题,如高填方边坡失稳、不均匀沉降等.为解决上述问题,本文针对机场高填方边坡工程,深入剖析高填方边坡施工中边坡高度、加筋层间距、筋材模量、压实度等参数对边坡变形影响程度,对于湿陷性黄土高填方边坡变形影响因素进一步认识及路基质量控制技术的提高和改进具有参考价值.
Abstract
With China's growing GDP,the infrastructure in the central and western regions needs to be improved urgently,and the construction of airports in the western region is developing very rapidly,but most of the airports are built in relatively remote places,and there are a large number of collapsible loess in the central and western regions.Therefore,the airport construction is facing a series of special problems,such as high fill slope instability and uneven settlement.In order to solve the above problems,this paper focuses on the airport high-fill slope engineering and deeply analyzes the influence of slope height,reinforcement layer spacing,reinforcement modulus,compaction degree and other parameters on slope deformation in the construction of high-fill slope,which has reference value for further understanding the influencing factors of collapsible loess high-fill slope deformation and the improvement of subgrade quality control technology.
