Rock-like material, and piezoresistance intelligent test system and method using rock-like material
The invention relates to a rock-like material, and a piezoresistance intelligent test system and method using the rock-like material. The rock-like material is composed of the following components in parts by mass: 400 parts of water, 1600 parts of aggregate, 800 parts of cement, 0-120 parts of silica fume, 0-4.5 parts of carbon fiber, 2.4 parts of a dispersing agent, 1.6 parts of a water reducing agent, 1.6 parts of a defoaming agent, 0-4 parts of basalt fiber and 0-15 parts of gypsum chips. The piezoresistive intelligent test system comprises a test piece, a sensor unit, a data acquisition unit and an image reconstruction unit, and the test piece is made of a rock-like material. According to the rock-like material provided by the invention, key characteristic parameters such as compressive strength, elasticity modulus and Poisson's ratio of a test piece can be adjusted by changing the proportioning ratio according to different experimental requirements. According to the test method provided by the invention, the defects of the traditional damage monitoring method are considered; wherein the dynamic damage degree of the rock similar material can be obtained by monitoring the real-time resistivity change of the model test piece by adding the novel conductive material carbon fiber into the rock similar material.
本发明涉及一种类岩石材料、使用类岩石材料的压阻智能试验系统及方法，所述类岩石材料按照质量份数由水400份、骨料1600份、水泥800份、微硅粉0～120份、碳纤维0～4.5份、分散剂2.4份、减水剂1.6份、消泡剂1.6份、玄武岩纤维0～4份、石膏碎屑0‑15份组成；所示压阻智能试验系统，包括试件、传感器单元、数据采集单元和图像重建单元，试件由类岩石材料制成。本发明提出的类岩石材料可根据不同实验要求，改变配料比来调整试件的抗压强度、弹性模量、泊松比等关键特性参数。本发明提出的试验方法考虑到传统损伤监测方法的不足，通过在岩石相似材料中加入新型导电材料碳纤维，可通过监测模型试件实时电阻率变化而获取其的动态损伤度。
