Tangent modulus method – An original method to measure in-situ rock stress [PDF]
Tunnelling and Underground Space Technology, 2018 Abstract This paper proposed Tangent Modulus Method (TMM) which is an improved oriented core method to determine in-situ rock stresses. In this approach, the cylindrical specimens prepared along different directions from thick core samples were uniaxially compressed twice to a given stress level.

Tangent Modulus Method, Applicability to Three Types of Rock and Influence of Confining Pressure
Journal of MMIJ, 2008 The tangent modulus method was applied to pre-loaded cylindrical specimens of Shikotsu welded tuff, Inada granite and Kimachi sandstone. It was clarified that the tangent modulus method could be applied to the rocks. A positive correlation was observed between the preloading duration and the maximum delay time at which the preloaded stress was ...

p-y curve method based on tangent modulus
Yantu gongcheng xuebao, 2021 It is still a hot problem to calculate the force of laterally loaded piles in engineering. At present, the p-y curve method is mostly adopted in international engineering specifications. Generally speaking, soft soil is different from sandy soil.
