摘要
该文针对我国沿海地区的管道工程中,常遇到工程性能很差的深厚淤泥及淤泥质土层,厚度可达数十米,易造成管道的不均匀沉降、管道施工中基坑失稳等问题,就此提出了一种新颖、经济、简便的管道基础形式,对其构造、技术特点及工作机理进行了介绍,并以工程实例进行阐述,提出了此种新型管道基础形式的注意事项。
In view of commonly meeting the problems of the worse engineering performance of deep silt and silty soil courses, which thickness can reach several ten meters and easily cause the unequal settlement of pipe, and the destabilization of foundation pit in the pipe construction in the coastal areas of China, the article puts forward a new, economic and simple pipe foundation form, and introduces its construction, technical characteristics and working mechanism, and sets forth it by the engineering practice and puts forward the proceedings for attention of this new pipe foundation form.
