Operating high-speed ballastless railway connection section widening roadbed structure and construction method
The invention relates to the field of widening roadbed structures, in particular to an operating high-speed ballastless railway connecting section widening roadbed structure and a construction method.The operating high-speed ballastless railway connecting section widening roadbed structure comprises an existing embankment and a light filling body, the existing embankment is provided with a side slope, and the light filling body is arranged on the side slope; a widening filling body is arranged on the side, away from the side slope, of the light filling body. The light filling body is filled with light filler, and the widening filling body is filled with common roadbed filler. According to the widening roadbed structure of the operation high-speed ballastless railway connecting section, it is avoided that the whole section of the widening roadbed is filled with light filler, the project investment is effectively reduced, and economic benefits are remarkable. On the basis of the allowable horizontal resistance of the existing operating high-speed ballastless railway embankment, the light filling body is filled with the light material, so that the weight of the light filling body is reduced, and the horizontal thrust borne by the side slope of the existing embankment is smaller than the critical thrust.
本发明涉及帮宽路基结构领域，特别是一种运营高速无砟铁路接轨段帮宽路基结构及构筑方法，运营高速无砟铁路接轨段帮宽路基结构包括既有路堤，所述既有路堤具有边坡，还包括设置于所述边坡上的轻质填筑体，所述轻质填筑体远离所述边坡的一侧设置有帮宽填筑体；所述轻质填筑体采用轻质填料填筑，所述帮宽填筑体采用普通路基填料填筑。本申请的运营高速无砟铁路接轨段帮宽路基结构，避免帮宽路基全断面填筑轻质填料，有效降低工程投资，经济效益显著。在既有运营高速无砟铁路路堤容许水平抗力的基础上，采用轻质材料填筑轻质填筑体有利于降低轻质填筑体重量，能够使既有路堤边坡所受水平推力小于临界推力。
