The Elastic–Plastic Damage Analysis of Underground Research Laboratory Excavation for Disposal of High Level Radioactive Waste
https://orcid.org/0000-0002-3081-3593
Abstract The deep geological disposal is an internationally recognized method for the disposal of high level radioactive waste. As an essential facility, the construction safety of underground research laboratory (URL) is very important. Taking the China’s first URL in Beishan, Gansu Province as engineering background, considering the influence of arranged joints in rock mass, an elastic–plastic damage numerical method for fractured rock mass is presented and the corresponding subprogram in Flac3D is developed. Based on the numerical calculation of underground research laboratory construction, the optimized excavation scheme of URL is obtained and the distribution rules of surrounding rock displacement field, stress field and plastic damage zone are studied. The research result can provide important guidance for the construction of Beishan URL.
