| | A and B dams(60 m and 46 m height respectively)both are earth structures constructed by dumping earth into ponded water.Because of the stability analysis of slows of these dams at the end of construction is an important control factor,thus in this paper describes the method of stability analysis based on the effective stress,which consists of three parts:. 1.The selection of indices of physical and mechanical properties of earth materials including laboratory determination of these property indices and thei... | | 本文以两个水中填土坝——A 水库土坝(高60米)、B 水库土坝(高46米)作为实例,用有效应力法进行了施工期和施工完毕时坝坡的稳定分析.主要内容分为坝体土料物理、力学性质指标的选择,包括士料的试验方法和指标的整理步骤,特别是孔隙压力系数和消散系数的确定;施工期及土坝刚建成时坝体孔隙压力消散的几个计算方法和步骤,即三相二元、三相一元,二相二元问题和孔隙压力不消散等四种计算方法;并结合有效应力稳定分析方法,提出了各种计算方法所得成果的比较.最后根据坝体的大小,推荐采用三相二元或三相一元问题的解答,确定施工期的孔隙压力大小. | | 文摘来源 | | The configuration of pore air and water as well as the structure of soil skeleton has great influences on the mechanical properties of partially saturated soils. In this paper three basic systems with different air-water configurations are postulated, namely, closedair system, bi-opened system and closed-water system. A closed-air system is defined as a partially saturated soil of such high degree of saturation that the air in the pore space forms isolated bubbles which are entirely enclosed by surrounding ... | | 本文根据土中的孔隙水-气形态,把非饱和土归纳为三种基本系统——水封闭、双开敞和气封闭系统。通过试验,证明了这三种基本水-气形态的存在,并给出了相邻两系统之间的临界饱和度约值。非饱和土的水-气形态的改变对其力学性质有着重大影响,并通过试验论证了两者之间的关系。 | | 文摘来源 | | This paper presents some important findings found from the researchs on soil liquefaction during the past two decades in the Water Conservancy and Hydroelectric Power Research Institute of China. They are the effect of stress condition on the development of excess pore water pressure in the course of soil liquefaction, the effect of the orientation and arrangement of sand grains upon the stability of the skeleton structure of the sands against vibratory action, the mechanism of development, dissipation$$... | | 本文介绍了近二十年来在我国水利水电科学研究院进行饱和土振动液化试验研究中发现的几个重要特性。它们包括应力状态对饱和砂土振动液化过程中孔隙水压力变化的影响,颗粒排列对砂土骨架结构振动稳定性的影响,饱和砂土在振动作用下孔隙水压力的产生、消散和扩散机理,以及粉土(少粘性土)液化可能性的评价准则等等。这些特性都是当今研究液化问题中被重视和感兴趣的题目。文中表达了作者对这些问题的看法。 | | 文摘来源 | |   | | << 更多相关文摘 |
