- Therefore , it is of significance in theoretic research and engineering practice to study the long - term strength of soft clayey rocks under immersion and unload
因而，对此类风化泥质软岩的浸水和卸荷长期强度的研究，具有十分重要的理论价值和工程实践意义。 - The basic physical and mechanical properties , mineral composition , micro structures , swelling potential , consolidated drained triaxial shear strength , parameters of constitutive model and residual strength of the soft clayey rocks were tested in laboratory with a large number of natural samples . the changing trend of the strength about these rocks is obtained by modeling the condition of softening due to immersion . from the principles of modern soil mechanics , the structural and swelling characteristics of soft clayey rocks were analyzed systematically
本文通过现场调查，查明风化泥质软岩的宏观结构特征，利用现代试验测试手段，取原状土系统进行特殊土室内土工试验，测定土的基本物理力学特性、矿物成分及微观结构、膨胀性、三轴排水剪强度及本构模型参数、软化残余强度，并模拟土体在长期浸水软化后的强度变化趋势，测试该类土的浸水软化残余强度。 - By studying the strength behavior to these rocks , their shear strength ranges were given in different engineering environmental conditions . based on a series of triaxial tests on the soft clayey rocks , parameters of the constitutive model are provided , which are necessary in numerical analysis and engineering computation . according to the results in this study , mechanism of deformation and failure of soft clayey rocks was explored , and the data on their physical and mechanical properties were collected in guangdong
结合现代土力学原理，系统分析了风化泥质软岩的结构特征，膨胀特性；探讨风化泥质软岩的强度特性，给出了风化泥质软岩不同工程环境条件下的抗剪强度取值范围；在三轴排水剪试验成果基础上，提供了工程数值分析和计算所需本构模型参数，揭示了风化泥质软岩的变形破坏机理，建立广东风化泥质软岩的物理力学性质特征资料，为工程决策提供参考。 - As far as the soft clayey rock , widely distributed in guangdong , is concerned , it will swell after unloaded and soften during immersion . its strength decreases with time after excavation . as a result , the slopes probably lose their stability in a long time , and in deed there are some failure cases reported in engineering
但对于在广东颇具代表性的风化泥质软岩，因开挖外露而导致的浸水软化和卸荷膨胀，会致使边坡岩土长期强度的减损，使得按岩土天然强度指标设计的边坡的长期稳定性无法保障，也造成了一些工程事故。
