软硬接触对含包体试样破裂模式影响的数值试验

Numerical Test on Influence of Weak & Hard Touching on Fracture Model of Specimen within Clusion

运用自行开发的岩石破裂过程分析系统RFPA2D,对包体与母岩间软、硬接触对包体试样破裂模式的影响进行了数值试验。研究认为 :软、硬接触对包体试样的破裂特征和试样最大承载力起着重要的影响 ,软接触对包体试样的破裂特征和最大承载力起着决定性的影响 ,而包体本身所起的作用并不重要。

Influence of weak & hard touching on fracture model of specimen with inclusion is simulated by using our RFPA 2D code.The results show that weak & hard touching has an utmost effect on fracture model of specimen with inclusion and the relation between load and displacement loading.Fracture model of specimen with inclusion,as well as loading capacity,is decided by weak touching,and has nothing to do with inclusion itself;while fracture model of specimen with inclusion,as well as loading capacity,is up to inclusion and mother rock when it is at hard touching.
