- Abstract:
- The fuzzy random reliability of earth-sheltered dwelling is researched in order to analyse the influence of loess mechanical parameters. Based on a cut sets , the fuzzy loess mechanical parameters are distributed in regions, and fuzzy random reliability problem is converted into random reliability problem. Due tostrength reduction method, relation between cohesive force, internal friction angle and excess safety factor isestablished, which is expressed by quadratie polynomial without cross terms and represents the performancefunetion of earth-sheltered dwelling. So the random reliability problem can be solved. The fuzzy random relia.bility research of earth-sheltered dwelling in Shan city, Henan province shows that, the reliability of earth.sheltered dwelling in this area is high, site selection is reasonable before construct, fuzzy random reliability in.dex is distributed in a region, checking point is constant, fuzzy random reliability index decreases sharply withcoefficient of variability increasing, and the influence of cohesive force on reliability index is higher than inter.nal friction angle.
