后注浆灌注桩在孟加拉某电厂工程中的应用

Application of Post-grouting Pile in the Power Plant Engineering Bangladesh

结合孟加拉某电厂工程后注浆灌注桩与普通灌注桩静载荷试验,介绍了灌注桩后注浆技术处理深厚充填沉积软土地层的施工工艺和控制参数,分别采用中标、美标和孟加拉标准对试验结果进行对比分析,确定后注浆灌注桩桩基允许承载力,采用后注浆灌注桩后承接力提高68.6%。

Combined with static load test of post-grouting pile and common pile,introduces construction technology and control parameters of the post-grouting pile consolidating thick sedimentary soft soil in Bangladesh power plant.By comparing the differences of bearing capacity test method and allowable value criteria among China,US and Bangladesh standards,the allowable bearing capacity of post-grouting pile is confirmed.After adopting post-grouting technology the bearing capacity increases by 68.6%.
