Abstract In order to further study the failure characteristics of freeze-thawed rocks in alpine region under multistage cyclic loads, a numerical simulation analysis was carried out with RFPA2D software, taking natural fractured granite from Beizhan Iron Mine Hejing County, Xinjiang Province as an example. The results show that degree fracture determines form rock, and when is large, rock will ...

Subsoil support is generally ignored in the design of reinforced piled embankments, resulting a very conservative for settlement control. This philosophy may lead to an unnecessary increase construction costs, especially embankments constructed over subsoil medium and high compressibility (i.e., compression index larger than 0.2). paper presents ground reaction lightly overconsolidated embankme...

experimental tests were performed to study the seismic behavior and performance ofmodified steel chevron braced frame systems, which incorporate a vertical slotted connection(vsc) detail between the top of the braces and the floor beam above. the vsc detail isintended to prevent vertical load transfer to the beam and limit brace forces to thecompressive resistance of the members. full-scale qua...

In offshore engineering, the sand beneath an embankment may be subjected to traffic loads, resulting in a series of engineering issues. The behaviour change under long-term load. A drained cyclic and post-cyclic monotonic triaxial tests were performed on Fujian with different relative densities. strength stress–dilatancy behaviours studied. results indicated that normalised peak ratio after loa...
