Expressway soft soil roadbed treatment method
The invention discloses an expressway soft soil roadbed treatment method which comprises the following steps: investigating the current situation of a roadbed soil layer and a foundation, looking up investigation data or supplementing investigation, determining a range and a depth of a soft soil roadbed, and combining fly ash filling and a dynamic compaction technology on the soft soil roadbed to solve the problem of an insufficient bearing capacity of the soft soil roadbed; in the first step, understanding the bearing capacity of the roadbed according to geological exploration data, carrying out detailed understanding on geological soil layer parameters, and determining a filler range and a thickness and the selection of a dynamic compaction rammer; in the second step, paving the fly ash mixed filler on the surface layer of the roadbed, and achieving a drainage effect through the gravity of a fly ash; in the third step, arranging a vertical drainage guide pipe, and draining water in the soft soil roadbed through the drainage guide pipe; in the fourth step, carrying out heavy dynamic compaction on the spread materials on the roadbed through a dynamic compaction machine so that the self-weight stress of the soil body is fully exerted; and in the fifth step, arranging the vertical drainage guide pipe to remove water in the soft soil foundation under the dynamic compaction effect.
本发明公开了一种高速公路软土路基处理方法，包括以下步骤：对路基土层及基础现状的调查，查阅勘察资料或补充勘察，确定软土路基范围及深度，在软土路基上进行粉煤灰填料与强夯技术相结合解决软土路基承载力不足问题；第一步，根据地勘资料了解路基的承载力对地质土层参数进行详细了解，确定填料范围、厚度及强夯夯锤的选择；第二步，将粉煤灰混合填料摊铺在路基表层，利用粉煤灰的重力达到排水的效果；第三步，布置竖向排水导管，将软土路基中的水通过排水导管进行排除；第四步，强夯机对路基上铺料进行重型强夯，使土体的自重应力充分发挥；第五步，设置竖向排水导管将强夯作用下的软土地基中的水分排除。
