Changing the depth of penetration of the three dowels results in the variation of the reflection coefficient ( s1 1 ) at the port 1 . using matlab , we can calculate different equivalent impedance of port 1 which resulted from the variation of dowels depth . the purpose of my work strike up a relationship between the depth of dowels and equivalent impedance at port , thereby accomplish matching rapidly , simultaneously and stably 在构建了自动阻抗匹配系统的基础上,本文提出了一种新的快速匹配方法;此方法是将仿真软件hfss和系统设计相结合,用hfss仿真系统中完成阻抗变换作用的销钉匹配器,获得销钉插入波导深度变化时的端口等效特性,并将仿真得到的数据用matlab组织起来,分析销钉插入波导的深度变化时端口等效阻抗特性的变化,来达到对调试变化规律的认识,快速的实现销钉插入深度与反射系数间的统一。
Based on finite element method , this paper analyzed and discussed the effects of the insertion depth and stiffness of the support structure , the braced position , the reinforced soil mass in a excavation engineering as well as brace prestress on the internal forces and deformations of the support structure and some suggestions for design of support structure are presented 以有限元法为基础，对支护结构的刚度、插入深度、支撑位置、坑内土体加固、预应力等因素对支护结构的内力和变形的影响进行分析，并得出有益的结论。
