Abstract

The invention discloses a geotechnical model test system based on macro-micro mechanics as well as an elaboration test method. The test system analyzes and processes shot digital images in a model test box in real time through two analysis systems in a computer. The test method organically integrates an indoor model test, field soil observation analysis of foundation soil, partial microscopic observation analysis, numerical value simulation of microscopic mechanics and continuous-discrete coupled numerical value simulation. The invention is suitable for the test research of geotechnical engineering such as building engineering, road engineering, bridge engineering, harbor engineering, river-coast engineering and coastal engineering, can solve common engineering problems and can upgrade the understanding level and the research level to important key problems, such as the influence on extreme environmental conditions of key project construction projects and engineering catastrophes, andthe like.

Description

Technical field: [0001] The invention relates to a geotechnical engineering test research method applied to basic construction projects, in particular to a rock-soil mechanics model test system based on macro-microscopic mechanics and a corresponding refined test method. Background technique: [0002] At present, model test methods, numerical simulation methods, and field test methods are mostly used in the experimental research of rock and soil mechanics in construction engineering, road engineering, wharf engineering, river coast engineering and offshore engineering. [0003] The model test method generally refers to the phenomenon research of the prototype physical system with a reduced (or enlarged) model under laboratory conditions, and the similarity requirements of the system must be met between the model and the prototype. The model test method can test the macroscopic physical quantity, but cannot test the mesoscopic structure of the soil sample directly observed. ...
