| | The purpose of this paper is to discuss Prof. method of analyzing two-way reinforced concrete slab. This method is based upon the equilibrium of forces under ultimate loading, and consequently the effect of plasticity of the material is included in consideration. If we use this method to design two way reinforced concrete slab, We should not only have much saving of steel, but also a saving of labour in computation. No matter that the slab is continuous over how many spans of unequal lengths, it can b... | | 本文的目的是介紹蘇聯格娃斯捷夫教授的計算双向板的公式。這個公式是考慮板在極限平衡狀態,考慮了材料的塑性。用此方法計算雙向板,不但鋼筋經济而計算簡便。無論是多跨的板或不等跨的板,都可以视為單跨板來考虑,本文討論了格娃斯捷夫公式的基本理論,並将此理論应用到不規则形狀板的计算方面。 | | 文摘来源 | | It is pointed out in this paper that the following apparent discrepancies exist in Coulomb's Theory: (1) In any problem in mechanics, a force to be definite must have all the three factors involved under consideration. In Coulomb's Theory, however, the point of application of the soil reaction on the plane of sliding is somehow neglected, thus enabling the arbitrary designation of the obliquity of the earth pressure on the wall to be equal to the friction angle between the wall surface and soil. As a matter... | | 本文從力學觀點對庫隆理論提出下列問題:(1)在解算力學問題時,每個力有三個因素都該同時考慮,但庫隆對土楔滑動面上土反力的施力點竟置之不理,因而才能對擋土墙上土壓力的傾斜角作一硬性假定,使它等於墙和土間的摩阻角,然而施力點是不能不管的,因而土壓力的傾斜角是不能離開平衡條件而被隨意指定的。(2)如果考慮了土反力的施力點,則土楔祇能在滑動面上,或在墙面上,有滑動的趨勢,而不能同時在兩個面上都有滑動的趨勢,因而庫隆的基本概念“滑動土楔”就站不住了。(3)問題關鍵在滑動面的形狀;如要使土楔在滑動面和墙面上同時有滑動趨勢,則滑動面必須是曲形面,然而庫隆採用了平直形的滑動面。(4)庫隆的土楔滑動面是從墙上最大的土壓力求出的(指主動壓力),這裏所謂“最大”是指適應各個滑動面的各個土壓力而言,但對適應墙在側傾時土壓力應有的變化來說,這個最大土壓力却正是墙上極限壓力的最小值。一般工程書籍,以為這土壓力既名為最大,就拿它來用作設計擋土墙的荷載,荷載如何能用最小的極限值呢?本文對朗金理論中的下列問題作了一些解釋:(1)朗金理論在擋土墙的位移問題上所受的限制,是和庫隆理論一樣的,竇薩基教授曾就此問題認為朗金理論是幻想,似乎是無根據的。... | | 文摘来源 | | The graphical method of virtual forces for determining the stability of slopes and foundations presented in this paper is based on the consideration of the statical equilibrium of the mass above any trial surface of failure. The method may be considered as an improvement of those proposed by H. Raedschelder Ghent and Professor Arisdocky (B. B. —U. S. S. R.), and is simpler and more reasonable than the "method of slices" which has been long used in our design work.When applied to determine the stabilit... | | 本文提出一个按圆柱形滑动面的假定来确定土坡稳定性的图解法,供研究参考。这个方法是参考H.Raedschelder Ghent(Belgium)土坡稳定分析的图解法及苏联B.B.阿利司朶斯基教授的土坡稳定计算法而推导出来的。在理论上,它比目前国内工程设计中仍在采用的条分法合理,而在运用上,它又比条分法以及上述的H.Raedschelder Ghent和B.B.阿利司朶斯基教授的方法简便,如果把这个作图法用之于地基稳定分析。它还能代替格立兴教授的地基稳定分析法,其方法较简易,而精确度并不差。 | | 文摘来源 | |   | | << 更多相关文摘 |
