换填法垫层厚度的优化设计

Optimization of Designs of Thickness of Bedding Courses Built with Method of Replacement

换填法地基处理设计关键是确定垫层的厚度。鉴于传统的设计方法存在不足,文章提出了一种改进的方法,经算例验证该法能更好地确定最佳垫层厚度,同时能适应不同的安全要求,具有较大的灵活性。

The key to the designs of soil improvement with the method of replacement lies in the determination of the thickness of the bedding courses. In view of the defects in the traditional design methods, the paper presents a modified design method, which was verified by examples of calculations and proved that the presented method can not only be used to better determine the thickness of a bedding course but can also be adaptable to different safety requirements with greater adaptability.
