Test study on distribution of base pressure of rigid pipe on flat soil foundation 平面土基刚性圆管基底压力分布的试验研究
Effects on final ground settlement with distribution forms of the contact pressure 基底压力的分布形式对地基最终沉降量的影响
The modified pdr method is used to design a practical projects . although the calculated average displacement of the building is less than the actual measurement . it is acceptable 对某工程实例进行了现场试验,测试了基底压力和桩顶反力,并对该工程作了沉降观测。
In this paper , the formulas of dynamic parameters provide good method to determine the dynamic parameters , which can reflect the influence of many factors such as the property of soil , the base area of foundation , the pressure of foundation , the exciting frequency and so on 本文得到的地基刚度、参振土质量和动力影响深度的计算公式能较好地反映地基土体性质、基底面积、基底压力和扰频等诸多因素对它们的影响,为更准确地确定机器基础系统的动力参数提供了一种较好的途径。
Five typical examples concerning pressure distribution under shallow foundation , earth pressure of retaining wall , behavior of a axially loaded bored pile , a metro tunnel constructed with shield machine , and a landslide with tunnels in it are solved successfully , which verifies the validity of the method developed in this paper . at the end , some unsolved problems in the presented method are discussed briefly 第页西南交通大学博士研究生学位论文上述工作完成后,应用该方法成功地计算了浅埋刚性基础基底压力分布、 5刚性挡土墙土压力、钻孔灌注桩承载特性、盾构法施工的隧道的受力及变形、隧道与滑坡的相互作用等儿种有代表性的岩土工程问题,证明了本文方法的正确性及用于岩土工程问题的可行性。
