公路施工中软土路基的施工技术处理

Construction technology treatment of soft soil subgrade in highway construction

路基是公路施工过程中非常重要的基础,也是必不可少的一项构造内容,对公路表面的负载能力有非常重要的影响和作用,能够直接对公路的整体施工质量产生影响。公路在施工过程中容易出现各种问题,但准备在先,所有问题都是可控的。软土路基施工技术就是保证公路施工不出问题的重要方面。软体路基施工技术有排水凝固法、换填法、爆破法、挖掘法、填埋法等,是有效解决路基沉陷、车辆跳车等现象的基本途径。在对软土路基进行施工处理时,要根据实际情况,选择先进的技术,巩固公路路基,达到工程质量有效提升的根本目的。

Subgrade is a very important foundation and an indispensable structural content in the process of highway construction,which has a very important impact on the load capacity of the highway surface and can directly affect the overall construction quality of the highway.Highway construction process is prone to a variety of problems,but preparation first,all problems are controllable.Soft soil roadbed construction technology is an important aspect to ensure that there are no problems in highway construction.Soft roadbed construction technology includes drainage and solidification method,replacement method,blasting method,excavation method,landfill method,etc.It is the basic way to effectively solve the phenomenon of roadbed subsidence,vehicle jumping and so on.When dealing with the construction of soft soil subgrade,we should select advanced technology according to the actual situation,consolidate the highway subgrade,and achieve the fundamental purpose of effectively improving the quality of the project.
