Large-scale model tests were established at a scale of 1/5 using 7 m deep tank with cross-sectional dimension 5 × 4 m, to study the vibration response characteristics ballastless track, embankment, and X-section piled raft foundation under cyclic axial load, including displacement, velocity, dynamic soil, pile stress. Cyclic loading can be achieved by controlling frequency cycles through servo ...

Foundation design must satisfy limited values of settlement. Settlement is an essential criterion in the design process of shallow foundations. To calculate the settlement under different types of shallow foundations, 79 samples were taken from twenty-three sites distributed in three regions: Mosul, Baghdad and Basrah in the northern, central and southern parts of Iraq. Field and laboratory tes...

In a combined piled raft foundation (CPRF) both and piles take their share of the total load applied. However, in practice, contribution taking is usually ignored assumed to be supported on piles. This way CPRF becomes excessively conservative uneconomical. To economize design, relative sharing has found. this connection, different simplified methods have been developed, each one with some limi...
