绪论单剪试验是试验应力和应变主轴随时变换的平面应变试验,这种试验较接近于许多实际工程中土体可能发生的情况。室内单剪试验,采用两种类型仪器进行,一种通称为“挪威土工学院”单剪仪(SSA),由彼塞姆和挪得瓦发明,试验采用圆柱形试样,外包橡皮薄膜,并用细琴线作螺旋形缠绕扎紧。这种仪器能测定平均水平力、平均垂直力和水平位移,而不能测得试样的应力状态。另一种仪器,首先由罗斯科提出,后由剑桥大学研制。试验将方形体试样装入刚壁盒内,这是相当低廉的精密仪器,可以测定试样全部应力状态。两种仪器的详细研究及
INTRODUCTION The single-shear test is a plane strain test where the stress and strain axes of the test are changed at any time, and this test is closer to what might happen to the soil in many practical projects. The indoor single-shear test was performed using two types of instruments, one commonly known as the “Norwegian Institute of Geosciences” single shear (SSA), invented by Biesem and Nodova, using cylindrical specimens, outsourcing rubber films, and The violin wire is spirally wound tightly. This instrument can measure average horizontal force, average vertical force and horizontal displacement, and cannot measure the stress state of the sample. Another instrument, first proposed by Roscoe, was developed by the University of Cambridge. The square shape test specimen is loaded into a rigid wall box, which is a very inexpensive precision instrument that can measure the entire stress state of the specimen. Detailed study of two kinds of instruments and
