Besides, this paper adopts the random finite element method, uses geometric and physical mechanical parameters that are relevant to lining weight of surrounding rock, coefficient of lateral pressure, height or buried depth of vertical loading, elastic resistance coefficients of surrounding rock, elastic modulus of support structure, unit weight of concrete, thickness of the structure as well as torsional strength and compression strength of concrete and etc., as random variables, applies the monte - carlo method to sampling by computer, preliminarily evaluates the reliability of bearing capacity and stability of molded concrete lining of the xuefeng mountain tunnel, and obtains the related displacement of the lining, mean value and variance of internal force, and computed the reliability index of lining structures
此外，本文採用隨機有限元方法，將圍巖容重、側壓力系數、垂直荷載高度或埋深、圍巖的彈性抗力系數、支護結構的彈性模量、混凝土容重、結構的厚度以及混凝土的抗扭與抗壓強度等與襯砌結構有關的幾何與物理力學參數作為隨機變量，應用蒙特卡洛理論進行計算機隨機取樣，對雪峰山隧道模注混凝土襯砌的承載力與穩定性的可靠度進行了初步評估，得出了襯砌的相關位移與內力的均值和方差，並計算出了相應的襯砌結構可靠指標。 -
But this method could n ' t reflect the influence of the variance of pile capacity on capping beam internal force and the partaking of soil to the load. combined with the item " the optimal design theory and research of pile capping beam " financed by natural science fund of hunan province, a new method which can consider the pile - soil interaction and tide over the disfigurement of the winkler soil model is used to adjust the foundation base reactions in this paper. by this method, the proper solution about the internal force of capping beam can be achieved and the relative stiffness and the relative position of soil spring are thought out well
本文結合湖南省自然科學基金項目「樁基承臺梁優化設計理論與方法研究」 ，考慮梁下土體和基樁對承臺梁的共同作用，提出了能對梁下地基反力進行自動調整的一種新型方法，其克服了文克爾地基模型所存在的缺陷，該法在調整過程中，充分考慮了梁下各土體彈簧之間的相對剛度，相對位置，更接近承臺梁的實際工作情況，有利於獲得承臺梁內力的正確解答。 -
Expanding capital operation, as an important part in development strategy, is closely related with the long - term development of listed companies, therefore, listed companies should hold strategical view in planning and making - decision in conducting expanding capital operation. based on sustainable development principle, the dissertation analyses the essence of expanding capital operation and its basic models according to the theories of capital operation ; combined with existing situation of china ' s listed companies, analyses internal causes and external factors which lead expanding capital operation falling into dire straits, and advances that using strategy is a breakthrough point to solve the problem. then, with the logical line of strategical management " analysis of strategical environment - settlement of strategical targets - drawing - up and choosing strategical model - implementing and controlling strategy - assessing strategy ", brings strategy into expanding capital operation process, analyses factors effecting expanding capital operation, and constructs decision - making model for choosing strategical styles ; in the implementation stage, focus on fixing exchange price and the whole integration management ; at final, using conglomerate m & a strategy as an example, utilizing entropic measure method, regression - analysis, variance - analysis and spss digital - statistic software, constructs a model to illustrate the relationship between diversified m & a strategy and economic performance of listed companies, puts forward the suitable expanding capital operation style for china ' s listed companies, and gives some suggestions
本文以公司持續發展為原則，根據資本運營理論，分析外擴型資本運營的內涵及其三種基本模式；並與我國上市公司的實際情況相結合，分析目前上市公司外擴型資本運營陷入困境的內在原因和宏觀因素，提出以戰略為支撐是我國上市公司外擴型資本運營走出困境的突破點；然後以"戰略環境分析-戰略目標定位-戰略制定及模式選擇-戰略實施與控制-戰略評價"的戰略管理邏輯主線，將戰略引入上市公司外擴型資本運營的各個階段，分析了影響上市公司進行外擴型資本運營的內外部因素、確立戰略性經營目標，構建我國上市公司外擴型資本運營戰略模式的決策模型；在戰略實施階段，重點研究交易價格的確定和全面整合管理；最後，以目前我國上市公司外擴型資本運營中常見的混合併購模式為例，運用熵測量法、回歸分析、方差分析等計量方法及spss大型數據統計軟體，構建模型，研究上市公司混合併購戰略與經濟績效的關系，在分析結果的基礎提出適合我國上市公司發展的外擴型資本運營模式及相關的建議。 -
Corresponding exploited computing procedures are introduced in this paper. furthermore, significant conclusions that can be applicable in practice are also summarized, after contrasting the datum from engineering instances and laboratory model tests, statistically analyzing the differences between dissimilar distributions of pile rigidity, different variance coefficients and various relativity, and probing into manifold factors determining the internal force distribution of pile capping beam and correlative principles
