英国剑桥自钻式旁压试验拟弹性段的非线性弹性模型毕安君（中国兵器工业勘察研究院北京１０００５３）０引言用弹性理论分析旁压试验拟弹性段的变形特征，是把应力、应变作为线性关系处理的。然而，由于自然土体具有非均质性和各向异性等特点，使旁压试验拟弹性段的应力，... Non-linear elastic model of quasi-elastic section of Cambridge self-drilling side-pressure test in China Bi Anjun (China Ordnance Industry Survey Institute, Beijing 100053, China) 0 Introduction The deformation characteristics of the pseudo-elastic section of the side pressure test are analyzed by elastic theory. It is the linearity of stress and strain. Relationship processing. However, due to the characteristics of natural soils such as heterogeneity and anisotropy, the pressure of the elastic section in the pressure test is...
