沿海砂质土地区深基坑支护技术的应用

Application of deep foundation pit supporting technology in coastal sandy soil

针对沙特沿海地区奥马尔市立交桥深基坑工程现状,利用有限元模型,结合国内外先进的深基坑支护技术,提出了"型钢支护桩+预应力锚索+方木挡土板"的综合支护体系,施工实践表明:该支护体系满足了基坑施工要求。

According to the current status quo of deep foundation pit engineering of coastal overpasses in Omar Saudi Arabia,the composit support system of＂steel supporting pile ＋ prestressed anchor cable ＋ wood block soil＂is proposed,combined with advanced technology of deep foundation pit and used the finite element to creat a model. The result shows that the system can satisfy construction requirements.
