摘要许多工程比如交通隧道、水工隧道、矿山隧道、地下仓库、地下工厂以及地下民用公共建筑甚至边坡都发生过较大变形或者失稳等情况,而造成这种情况的重要原因之一就是岩石蠕变。近几年来,随着我国一些修建堤坝、溢水道、水、渠道等工程,逐渐发现了岩石的蠕变特征在渗流作用下越来越明显,这也对许多工程的长期稳定带来了很多有害影响。然而在相关领域并没有对这种情况展开细致而又紧密的试验,也没有对相关的试验设备进行改进与完善。因此,本文设计了一种岩石在渗流作用下探索蠕变的方法,提供新的研究思路以及研究方法应用于保证岩石工程的长期稳定性方面。75742 本设计主要进行试验,首先将现在存在的一些可以研究岩石在渗流作用下蠕变的特征的试验系统或者试验设备进行了改进,加之以完善,开发了新的渗流蠕变耦合试验系统和试验方法。本设计以破碎岩石为样本,进行了渗流蠕变耦合试验,并探讨了岩石在渗流作用下的蠕变特征,即应力、渗流对破碎岩样的影响。 该论文有图28幅,表格8个,参考文献15篇 毕业论文关键词:渗流 蠕变 渗透性 耦合试验系统 Seepage Coupled Creep Test System Abstract One of the many engineering examples show that traffic tunnels, hydraulic tunnels, mining tunnels, underground warehouses, underground factories and public buildings and even underground civil slope have occurred in other large deformation or instability situation, and an important reason for this situation It is rock creep。 In recent years, with some of China's construction of dams, spillways, water channel and other projects, and gradually find the creep characteristics of rock under seepage increasingly evident, which is also the long-term stability in many projects has brought a lot of harmful effects 。 However, this situation did not carry out a detailed test but closely related fields, nor the associated test equipment to improve and perfect。 Therefore, this paper designed to explore a rock creep under seepage methods, provide new research ideas and research methods applied to ensure long-term stability of rock engineering。 The design of the main test, the first research now exists that can rock creep under seepage characteristics of test systems or test equipment has been improved, combined with improved, developed a new seepage coupling creep test systems and test methods 。 This is designed to break the rock samples for seepage coupling creep test, and discusses the characteristics of rock creep under seepage action, namely stress, the impact on the flow of crushed rock samples。 Key Words: Seepage Creep Permeability Coupling Test System 目 录 摘要Ⅰ Abstract--Ⅱ 目录Ⅲ 图清单-Ⅳ 表清单-Ⅴ 1绪论--1 1。1蠕变的含义1 1。2研究背景及意义--1 1。3目前研究现状-3 2试验系统的整体设计目标--9 2。1试验系统功能-9 2。2试验系统性能指标--11 2。3本章小结-12 3试验方案设计--13 3。1总方案设计--13 3。2各功能方案设计-14 3。3本章小结-21 4试验系统的结构设计--22 4。1渗流仪的设计22 4。2液压缸的设计31 4。3液压加载系统设计--40 4。4本章小结-43 5 总结-44 参考文献--45 致谢47
