The total and differential settlements of representative sites were computed with layer wise summation method in conjunction with typical section of Shanghai-Nanjing expressway.

The parameters of the construction was studied and optimized by use of numerical simulation methods. At the same time, the behaviour of typical section of the project was assessed.

For the typical section of the encircling ring, the bleacher roof is supported on the hybrid beams that composed of steel ribs bolted with glulam and reinforced concrete independent walls.
