新兴铸管厂主储料场建于尾矿砂、碎石土堆填冲沟沟口宽敞地带,拟建火车卸料平台高差15.0m。鉴于平台填料工程地质、所处环境特征与支挡结构功能特点,经多种方案比较,采用了二级重力式组合挡墙、兼具铁路路基与卸料平台的综合设计,结构新颖,设计独特,成功地解决了支护、路基与卸料有机结合的复杂难题。为同类条件下的支护结构设计提供了有益的借鉴。 Xinxing Ductile Iron Piling Plant owners storage yard was built in the tailings sand, gravel soil fill the gully ditch spacious area, the proposed train unloading platform elevation 15.0m. In view of the platform packing engineering geology, the environment characteristics and the features of the support structure, the two-stage gravity combined retaining wall is adopted by a variety of schemes. It has the integrated design of railway subgrade and unloading platform with novel structure and unique design , Successfully solved the complicated problems of supporting, embankment and unloading combined organically. It provides a useful reference for the support structure design under the same conditions.
