在设计和兴建大型水利水电工程的过程中,常常会遇到断层破碎带、软弱夹层、大的节理裂隙等。这些地质构造对建筑物的抗滑稳定,不均匀沉陷和上部结构的应力分布等,都有不利的影响。为了研究水工建筑物的抗滑稳定安全度和基岩的破坏形式,以便采取有效的工程措施,来加固和保证建筑物的安全运行,因此必须进行地力学的整体模型试验。 随着国内外对地力学模型试验的不断开展和研究,因之也相应对模型材料的要求愈来愈严格了。一般说来,地力学模型材料要求具有高密度、低弹模和低强度。(弹模约自几 In the process of designing and constructing large-scale water conservancy and hydropower projects, fault fracture zones, weak sandwiches, and large joint fractures are often encountered. These geological structures have adverse effects on the stability of the building, uneven subsidence, and stress distribution of the superstructure. In order to study the stability of anti-sliding stability of hydraulic structures and the form of bedrock damage, in order to take effective engineering measures to reinforce and ensure the safe operation of buildings, an overall model test of geomechanics must be conducted. With the continuous development and research of geomechanical model tests at home and abroad, the requirements for model materials have become increasingly stringent. In general, geomechanical modeling materials require high density, low elasticity, and low strength. (The bullet is about from several
