摘要
在基坑工程支护结构的内力与变形计算方法中,弹性地基杆系有限元法具有概念清晰、计算简单、计算参数较少、易于模拟工程实际等优点,在挡土结构设计分析中具有独特的优势.通过对弹性地基杆系有限元的进一步研究,编制了相应的计算程序,进行了实例验证与对比分析.研究表明,弹性地基杆系有限元法是深基坑内力与变形计算的一种实用而有效的方法.
Among lots of calculating methods of internal stress and deformation about surrounding frame of deep foundation pit, finite element method of bar system was good in clear conception, calculating simply, less calculating parameters and simulating project practice easily and so on, therefore, it had special advantages in design analysis of structure of keeping off soil. With finite element method of bar system of elastic foundation researched uheriorly, the corresponding numeration program is worked out, and the real examples are validated as well as the contrast analyses are carried out. The study shows that finite element method of bar system is a kind of applied and effective method of calculating internal stress and deformation about deep foundation pit.
