广州港南沙港区四期工程采用自动化轨道式龙门起重机(ARMG),ARMG对地基基础的要求较高。由于原状软土厚度较大,大面积真空预压处理的地基不能满足使用要求,需要对轨道地基进行二次处理。结合工程地质条件和ARMG使用要求,通过方案比选,采用水泥搅拌桩复合地基对轨道进行二次地基处理。堆场区轨道基础采用钢筋混凝土地基梁结构+水泥搅拌桩复合地基,过路段轨道基础采用钢筋混凝土轨道板结构+水泥搅拌桩复合地基。钢筋混凝土地基梁+水泥搅拌桩复合地基方案可以满足轨道的使用要求,造价较低、过路段差异沉降较小。 相似文献

新近吹填淤泥目前主要采用真空预压二次处理技术(浅层+深层)进行加固,施工成本较高、工期较长。基于新近吹填淤泥的真空固结机理,提出优化现行真空预压排水系统的新思路,依托广州港南沙港区三期工程软基处理II区工程,开展新型真空预压排水系统现场试验研究。结果表明,新近吹填淤泥经地基新型真空预压排水系统加固后,达到设计要求,解决了现行真空预压排水系统应用于新近吹填淤泥地基时所存在的排水板堵塞、真空压力传递效率低下等问题,且有效地缩短工期、节约成本;基于真空压力传递特性及最终加固效果,方案3 (原生料防淤堵型整体式排水板+专用接头+水平排水板+粉细砂垫层)更适用于新近吹填淤泥地基。 相似文献

真空预压在淤泥地基处理中的应用 总被引:1,自引:0,他引:1
<正> 黄骅港煤码头工程陆域是围海和吹填形成的泥塘。原设计为堆载预压加固该地基。而在施工时出现机械沉陷、施工难度大且工程进展慢的现象。承担该项施工任务的中港一航局四公司同建设单位及设计单位协商,变更为真空预压加固法,为一期工程提前3年完成和二期工程加速建设发挥了积极作用。 相似文献
