MMA is produced by the method of acetone-cyanhydrin mainly in our country. The synthetic route is complex, the technical line is long, and the yield is low with high cost after many steps. Hydrocyanic acid is used as raw material, the treatment of numerous waste acid is difficult . Furthermore, concentrated sulfuric acid consumed in this method corrodes equipments and pollutes the environment seriously.
我国MMA的生产以丙酮腈醇法占主导地位,合成路线复杂,生产工艺长,多步反应后产率低,成本高,其采用有剧毒的氢氰酸为原料,产生大量难于处理的废酸,所消耗的浓硫酸对设备腐蚀性大,对环境污染严重,因此开发新的MMA工艺路线很有必要。

The model can reflect the multi-sets feature of the rock masses in practice, consider the influence of the joint orientation and strength to the rock masses deformation feature, and simulate the simultaneous sliding, tension and close behaviors of the multi-sets jointed rock masses extending the joint surface, and reflect the plastic deformation induced the rotation of the principle stress axes. The result can be extended to fractured rock masses with arbitrary set joints.
该模型能反映实际工程中岩体的成组节理特性,考虑节理产状和强度对岩体变形特性的影响,可用来模拟岩体中多组节理同时存在滑动、张开、闭合的行为,并能反应由于应力主轴旋转所产生的塑性变形的影响。
