复合地基控制桥头地基沉降的应用

On the Use of the Measures to Control the Bridge Composite Foundation

分析了桥头跳车的原因,介绍了桥头跳车的应对措施。并根据桥头地基沉降的具体情况,采用CFG桩、载体桩2种桩型复合地基对桥头地基沉降进行处理,对其中的控制效果进行观测和分析。结果表明,在桥头地基沉降控制的实际工作中,CFG桩复合地基或载体桩(由混凝土、夯实填充料、挤密土体和混凝土桩一起组成的具有承载作用的桩体)复合地基对沉降有着良好的控制效果,满足了桥头地基沉降控制的实际需要。

This paper analyzes the reasons of b at the bridgehead, and vehicle bumping at bridgehead. According to the specific situation of CFG pile and pile with bearing base two kinds of pile composite founda tion settlement. The control effect will be observed and analyzed. The work of settlement control of bridge foundation, CFG pile composite base composite foundation has a good control effect on the settlement, ment control of bridge foundation. It is worthy of further promotion neermg process. bridge tion are results introduces measures of foundation settlement, used for bridge founda- show that, in the actual foundation or pile with bearing it satisfies the and application needs of settle in similar engineering process.
