Embankment reinforcing system for liquefiable site reinforced gravel pile composite foundation and reinforcing method
The invention belongs to the field of foundation reinforcing engineering, and relates to an embankment reinforcing system for liquefiable site reinforced gravel pile composite foundation and a reinforcing method. The reinforcing system involves two-way reinforced gravel piles, a sheet pile wall, a geotextile cushion layer, a geogrid reinforced gravel cushion layer, a horizontal drainage channel, drainage ditches, a sand cushion layer, an embankment filling layer and an asphalt concrete surface layer, wherein the reinforced gravel piles are constructed through a vibroflotation method and are arranged in a square shape to form a vertical drainage channel, the geotextile cushion layer, the geogrid reinforced gravel cushion layer and a second geotextile cushion layer are sequentially laid on the upper portions of the two-way reinforced gravel piles to jointly form the horizontal drainage channel, the drainage ditches are formed in the two sides of the horizontal drainage channel, the sand cushion layer is arranged at the top of the horizontal drainage channel, and finally, the embankment filling layer is built on the top surface of the sand cushion layer. The embankment reinforcing system for the liquefiable site reinforced gravel pile composite foundation and the reinforcing method are easy and convenient to construct, short in construction period, low in cost, higher in bearing capacity and liquefying resistance, the embankment reinforcing system for the liquefiable site reinforced gravel pile composite foundation and the reinforcing method which are economical and efficient are provided.
本发明属于地基加固工程领域，涉及一种可液化场地加筋碎石桩复合地基路堤加固体系及加固方法，该加固体系包括双向加筋碎石桩、板桩墙、土工布垫层、土工格栅加筋碎石垫层水平排水通道、排水沟、砂垫层、路堤填土层和沥青混凝土面层；加筋碎石桩通过振冲法施工，按正方形布置，组成竖向排水通道；在双向加筋碎石桩上部依次铺设土工布垫层、土工格栅加筋碎石垫层和第二层土工布垫层，共同组成水平向排水通道，并在水平排水通道两侧设置排水沟；在水平向排水通道顶部设置砂垫层；最后在砂垫层顶面修筑路堤填土层。本发明施工简便、工期短、成本低，并且具有较高的承载力和抗液化能力，提供了一种经济高效的可液化场地复合地基路堤加固体系及加固方法。
