圆形煤场设计方案比较

Comparison of Design Scheme of the Circular Coal Yard

针对某电厂圆形煤场所处地质条件不良,经处理后的地基仍无法满足煤场区域基础承载力要求情况下,对几个软土地基处理方法优缺点进行比较分析,最终选择刚性桩法、冲孔灌注桩方案对地基进行处理;整体式挡煤墙采用侧壁整体式挡煤墙、堆煤区采用桩筏基础。该设计方案受力合理,整体性能好,结构安全,整体造价最低。其他类似项目可作参考。

Considering a detailed case of certain power plan that the geological condition of circular coal yard location is poor and even after improvement the subgrade still couldn’t satisfy the requirement of foundation bearing capacity for coal yard area, several treatment schemes for soft soil foundation have been analyzed with respect to advantages and disadvantages. Finally, rigid-pile scheme and punched cast-in-situ pile scheme are chosen for subgrade treatment;monolithic coal-retaining side wall is applied for coal-retaining wall and piled raft foundation is used in coal yard area. This design scheme provides reasonable force-carrying, favorable integrality, safe structure and the lowest overall cost. This scheme could be A to for other similar projects.
