The effect of expansive concrete on the side resistance of sockets in weak rock

In situ load tests and theory are used to investigate the effectiveness of expansive concrete on the improvement of side resistance of sockets in weak rock. Two in situ load test databases are used where rock sockets are constructed with normal and expansive concrete. Both databases include the side shear stress-displacement relationships, the rock mass properties and the socket geometry. Using the side shear stress-displacement relationships,...
