Abstract: Tunneling efforts that use shield machines often encounter weak and fractured rock formations, where the stability of the tunnel face is the principle safety control factor during tunnel construction operations. Within the ...

Abstract: In order to study the influence of friction wheel parameters and loading eccentricities on the horizontal bearing characteristics of pile-wheel hybrid foundations, the numerical calculation models of pile-wheel hybrid ...

Abstract: During tunnel construction, the excavation face frequently encounters heterogenous weathered composite strata that considerably reduce tunnel face stability. To assess the stability of the tunnel face under such conditions, ...
