Because of limit that invisibility and discommodious in anciently program , based on the method of limited rigid body equilibrium , using visual program language vb and connect autocad , realize plane and solid programme of abutment analysis of arch dam , provide alternation interface for designer . presently , our country constructing and will construct high 300m arch dam , it is important to judge security based on nonlinear fem analysis . basic theory of nonlinear fem analysis and its realization in ansys were studied 针对传统程序的存在问题,非直观、不易操作特点,以刚体极限平衡法为基本分析方法, visualbasic作为操作平台,结合autocad图形软件,完成了刚体极限平衡法二维、三维坝肩稳定分析程序设计,使之具有直观性,可视性、易操作性,为设计人员提供了具有友好界面的工程使用软件目前我国西部在建和将建一批300m级的高拱坝,运用有限元方法计分析拱坝稳定性、评判大坝安全度十分有必要。
Firstly , for the system of moulding board and support frame in construction the side pressure and screws are analyzed . the material and structure form of support frame are discussed . the design of support frame uses the method of limited state , and also it analyses the integer stability , part stability , and single stability , and then proposes the load analysis of multi - level support frame 首先,针对转换层梁模体系及支撑架施工,重点分析了转换层结构现浇混凝土对模板侧压力值及模板对拉螺杆的计算;讨论了转换层支撑体系的形式及构造,详细论述了基于极限状态设计的支撑架计算方法,包括纵横向水平杆的强度验算、立杆的整体稳定性、局部稳定性、单肢杆件稳定性等验算,并提出了多层支撑架的施工荷载计算方法。
Third , modeling and calculating of blast scheme : modeling and calculation of blast were made with nonlinear dymanic fem software - dyna2d . the effect rule of blast on slope stability was summarized . fourth , analysis and calculation of rock slope stability : the sarma method of limit equalibrium and fem method were used to analyzed the stability of rock slope in the test road part 爆破方案模拟计算:采用非线性动态有限元dyna2d程序,对所做爆破方案进行数值模拟计算,总结爆破对边坡的稳定性影响规律;边坡岩体稳定性计算与分析:利用极限平衡分析的sarma法利数值分析的有限单元法,对实验路段的岩质边坡进行稳定性分析。
On basis of ship strength theory , mathematical model and solvable method of limited deflections of ships are established , and deflection criterion to check the demands of longitudinal strength of intact ships or damaged ships is proposed . it is convenient for the preliminary ship design 根据船体梁强度理论,建立船舶极限挠度数学模型与求解方法,提出利用船舶挠度检验船体总纵强度的新方法,可以较方便地对正常或破损船舶总纵剩余强度进行检验,便于初步设计。
In this paper , the author will introduce the concept and the origin of abuse of litigious rights , and the situation of the research and innovation about the theory and the institution of it . some theoretical base of limiting abuse of litigious rights will be analyzed , such as the principle of good faith , and due process . at the end of the article , the methods of limiting the abuse of litigious rights will be introduced , by refer to the foreign ’ s success experience and the condition of our country 本文系统分析了诉权滥用的概念和诉权滥用产生的原因及评判标准,以及诉权滥用理论及制度的研究发展状况,进而详细分析禁止诉权滥用的理论基础;这同时为制约诉权滥用提供了理论依据,即结合本国特点又借鉴其他国家对诉权滥用行为制约已形成的成功经验,本文尝试着在原则和具体规则两方面对诉权滥用行为进行制约,并建议对我国的诉讼制度进行完善。
