摘要

对利用原位直剪试验法向压缩变形曲线求取弹性模量的两种传统方法进行了分析和探讨，认为利用压缩曲线法和间接现场荷载试验法的经验公式计算出的结果均小于实际值。提出了一种新的利用原位直剪压缩曲线求取弹性模量的综合方法，同时采用3种方法求取了岭澳3期工程强风化角岩的弹性模量。分析表明，原位直剪试验压缩曲线综合法求得的弹性模量为压缩曲线法与间接现场荷载法取值之和，其计算原理与直剪试验法向加载时力学变形机制一致，计算值更接近于真实值，有效地解决了边坡岩体变形稳定性分析中弹性模量取值问题。

Abstract

Through the discussion and analysis of the two traditional computing method of elastic modulus with the normal compressed deformation curve of in-situ direct shear test

which indicate that the real value is bigger than its directly calculated modulus of confined compression and the modulus calculated by the empirical formula of the in-situ load test. A novel integrated method is proposed to calculate the elastic modulus with the in-situ direct shear compression curve. At the same time

the three methods are used to calculate the elastic modulus of highly weathered hornfels in Lingao Ⅲ. The elastic modulus calculated with integrated method of in-situ direct shear compression curve is the sum of the directly calculated modulus of confined compression and the modulus calculated by the empirical formula of the in-situ load test. The calculating principle of integrated method is consistent with the mechanics and deformation mechanism of direct shear test with normal direction load. The calculated value is more close to the real value with which the problem of calculating elastic modulus is resolved effectively in the stability analysis of slope rock deformation.
