This paper presents shakedown analysis of a half-space obeying Von-Mises criterion under Hertz loads in plane strain model. Based on the static shakedown theorem, a rigorous shakedown solution is established by searching...

Based on a large-scale excavation adjacent to metro line, the design and construction schemes and monitoring data of metro structures during construction are analyzed. Some conclusions are drawn as follows: the movement ...

The case study of closely spaced twin tunnels excavated vertically beneath the adjacent Chaoyangmen station in Beijing, China is introduced. The existing subway station is part of the Beijing subway Line 2. The new recta...

La propuesta de este trabajo es estudiar una región -que es primero Territorio Nacional desde 1881 y luego provincia a partir de 1953- definida como marginal, en tanto espacio que se incorpora tardíamente y en condicio...

Este artículo se propone comprender y describir las estrategias de construcción del acontecimiento en tres medios gráficos del espacio mediático argentino. El análisis del proceso de sentido del Caso Nisman, en plen...

The discontinuities distributed in underground structures are the important factors that affect the mechanical characteristics of rock mass, and to study the mechanical behavior of rock discontinuities under cyclic loadi...

A hybrid technique, FEM-IBIEM is developed for studying the scattering of seismic waves by a 3-D complex local site. The indirect boundary integral equation method (IBIEM) adopts the dynamic Green's functions of concentr...

Qwing to that the common cement paste used in the complex soil strata with wide steep seams and loose space cannot fill firmly and run along the gaps, a new type of SJP cement paste is developed, which has great initial ...

Based on the Biot's theory of the two-phased poroelasticity medium, a coupled model for a saturated layered ground containing an open trench and track is developed, and the effect of the open trench on reducing the vibra...

Based on the framework of thermodynamics and critical state soil mechanics, a new α-β yield surface is formulated in the triaxial space. Based on the non-associated flow rule and bounding surface framework, the propose...

Based on the concept of true stress and the strain equivalence hypothesis, a three-dimension elastic-plastic damage constitutive model for rock is established. Combining the nonlinear unified strength model as the yield ...
