本论文在对这两种方法进行认真的分析后,说明它们对不连续面的描述并不合理,也无法反映出不连续面的主要力学特性,同时指出,将带有不连续面的岩土工程问题作为接触问题计算更为合理,它可将不连续面受力变形的主要特点反映出来,即:(1)接触面具有相应的&抗剪强度&,即当接触面上某一点处的切向应力小于该点处的抵抗强度时,点对共同变形;达到强度时,则沿切向发生相对滑动;(2)在整个变形过程中,发生接触的变形体不能相互侵入。

At the same time, the finite staff element method is used to analyze the influence of beam rigidity; and the two new methods proposed are used to analyze the influence of connect way between piles and beam; and the conclusion is obtained that the rigidity ratio between beam and piles being 0.48 is appropriate; the continuative increase of the rigidity ratio is not significant; the worst condition is that connecting way between piles and beam is hinged; the best condition is that connecting way between piles and beam is rigid. Whether is single-row pile or are double-row piles, when the front of single-row pile or the front of the front-row pile(in the double-row piles) needed excavation, it is supposed to that ought to be carefulness to excavate, because it is that the engineering cost increased greatly.

同时,用有限杆单元法,对双排桩的连梁刚度和用文中提出的方法以桩梁连接方式进行了试验和理论分析得出如下结论:在满足不相互影响排桩间距的情况下,桩顶连梁与桩的刚度比不小于0.48是合适的,此时再增加连梁刚度无意义;桩梁连接为铰结时双排桩受力变形性质最差,刚结时受力变形性质最好;不论是单排桩还是双排桩,桩前和前排桩桩前土体需要开挖时应慎重,因为这种开挖对支护结构影响很大,造价增加很多;双排桩省钱,而且抵抗变形的能力强,值得在工程中研究和广泛应用

Based on long-term monitoring convergence deformation of Wuqiaoling deep-buried long tunnel, this paper analyzes convergence deformation regularity of two parallel main tunnels. Results show the left main tunnel's convergence obviously exceeds that of the right, because the right main tunnel's construction absorbs the experience of the left main tunnel. Furthermore, authors research on rheology rule of Wuqiaoling tunnel by FLAC(superscript 3D). Numerical analysis result basically is consistent with actual measurement result. Finally, 6 principles to dispose soft wall rock rheology are presented.

Long periods of seeming invincibility. Though some industries or lines of business exhibit characteristics that endow leaders with virtually insurmountable advantages, and that tend to establish Survival of the Fattest as almost a natural law, most do not. Thus, for every Inevitable, there are dozens of Impostors, companies now riding high but vulnerable to competitive attacks. Considering what it takes to be an Inevitable, Charlie and I recognize that we will never be able to come up with a Nifty Fifty or even a Twinkling Twenty. To the Inevitables in our portfolio, therefore, we add a few "Highly Probables."

在所属的产业都被赋予其无可取代的优势地位,大者恒存的自然定律似乎牢不可破,但实际结果却不然,也因此在找到真正的真命天子之前,旁边可能还有好几打假冒者,这些公司虽然曾经红极一时,但却完全经不起竞争的考验,换个角度来看,既然能够被称为永恒的持股,查理跟我早就有心理准备,其数量绝对不可能超过五十家或甚至是不到二十家,所以就我们的投资组合来说,除了几家真正够格的公司之外,还有另外几家则是属于极有可能的潜在候选人。
