| 摘 要： | 由于冰碛土粒度组成和沉积结构的特殊性，无论室内试验还是原位试验，均难以获取冰碛土体可靠的强度和变形指标，因而强度值的合理选取一直成为冰碛土体工程设计和评价的瓶颈。采用元胞自动机方法模拟冰碛土体结构，构造仿真的大型试体，借助于FLAC3D，对模拟试体进行了三轴数值模拟试验，并依据常规三轴试验的力学公式求得了冰碛土体的强度和变形参数，从而为岩土体强度试验提供了一种崭新方法，为虚拟岩土实验室的建立作出了有益的尝试。

| Abstract: | Because of the particularity of size composition and sedimentary texture of glacial till,reliable parameters of strength and deformation aren't obtained by both laboratory test and in situ test.As a result,it is a difficult problem to choose proper strength parameters in engineering design and evaluation of glacial till all the time.Cellular automation method is adopted to simulate structure of glacial till and construct large-scale emulational trier.Afterward,triaxial numerical simulation tests are carried... |
