The foundation engineering is typical in both excavation depth and scale , on the basis of in - situ investigation , the design optimistic of retaining wall was discussioned in this paper , the mian reseaches including : the using of fem optimazition methods of rods system ; the delvopment of programs for optimazition of imbedding depth of structure based on matlab and for whole design optimaziton of the retaining structures based on ansys , under the two controlling factors of the saft coefficient and the reliability probability about the whole damage of retaining atructure ; the analysis on the m index of soil , the depth of retaining structures imbedded in the rock and the overall optimistic design of retaining structures 该基础工程不论在开挖深度还是规模上都很具有代表性。作者在现场调研的基础上，探讨了基坑支护结构设计优化问题。主要研究内容可以归纳为：应用基于m法的弹性地基梁杆系有限元方法；在围护结构整体稳定性安全系数与可靠性破坏概率两种控制因素下，编写了嵌岩深度优化的matlab程序与围护结构整体设计优化的ansys批处理程序；进行了地层抗力比例系数反算、地下连续墙嵌岩深度优化与地下连续墙结构体系整体设计优化。
Describes the third and fourth of six strategies for grid application enablement outlining how the work of a batch program is subdivided and how a program becomes a service subroutine callable by a client through grid middleware . part 4 of this series describes new paradigms that can be exploited when an application uses services in parallel 描述了启用网格应用的六种策略中的第三和第四种，概述了如何将批处理程序的任务进行划分，以及程序如何成为可供客户机通过网格中间件来调用的服务子例程。
