岩土体的φ、C值指标的确定主要是靠取样室内试验和现场原位试验。目前国内外工程地质勘测及岩体力学试验中多用<多点法>,即用三块以上岩样求出τ-δt_gφ+c关系曲线。其特点是现场原位试验,因制备试件往往非常困难,特别对一些软弱岩体就更困难;而且要打试验平硐,试验费昂贵。为解决这一课题,江西工业大学土建系张景德、宋寿南等人,经过
The determination of the φ and C values of rock and soil mass mainly depends on sampling indoor tests and on-site in-situ tests. At present, the multi-point method is commonly used in engineering geological surveys and rock mechanics tests at home and abroad. That is, the relationship between τ-δt_gφ+c is obtained from three or more rock samples. It is characterized by on-site in-situ tests. It is often very difficult to prepare specimens, especially for some weak rock masses, and it is expensive to test flat specimens. In order to solve this problem, the civil engineering department of Jiangxi University of Technology Zhang Jingde, Song Shounan and others passed the
