用打入予制桩加固软土地基是国内外工程建设中长期广泛应用的重要方法,在我国沿海软土地区也有近五十年使用经验。由于予制桩在穿透高压缩性软土达到较坚硬的持力层后,。具有较高的承载力监可大量减少建筑物的沉降变形,因而技术可靠,经济合理,施工也快速简便。随着近代技术的发展,打桩施工机械和工艺不断更新,应用范围正不断扩大。
It is an important method for long-term and extensive application of domestic and foreign engineering construction to reinforce soft soil foundation with pre-cast piles. It also has nearly 50 years of experience in coastal soft soil areas in China. Because the pre-piles penetrate the high compressive soft soil to reach a harder holding layer. Having a high bearing capacity can greatly reduce the settlement deformation of the building, so it is technically reliable, economical and reasonable, and the construction is quick and easy. With the development of modern technology, piling construction machinery and technology are constantly updated, and the scope of application is continuously expanding.
