Research on analytic calculation model for mining induced stress in multi-layered floor rock
矿业科学学报, 2017 Considering the layered structure of floor rock masses, the calculation model for mining induced stress of multi-layered floor rock is established.First, the transfer matrix relating the abutment pressure and stress and displacement components of floor ...

Monitoring of a bridge with integral abutments
, 2009 Preliminary results obtained from short term test-loading are used to illustrate possibilities of FEM used to calibrate complex interaction characteristics between a pile and soil in a bridge with integral abutments. The measurements are obtained during the winter season on the bridge over Leduån, in Northern Sweden.

Towards a Better Understanding of Behaviour of Bridges with Integral Abutments
Composite Construction in Steel and Concrete VI, 2011 One of the issues that has not been completely resolved in bridges built without expansion joints is the influence of seasonal temperature variations and soil characteristics on the maximum bridge length. To study this problem, a 40 meter long road composite bridge over the river Leduan in the north of Sweden was built in 2005.
