The two inverse analysis approaches capture well lateral wall deflections and maximum surface settlements.
An alternative method of maximum ground surface settlement prediction, which is based on integration between wavelet theory and Artificial Neural Network (ANN), or wavelet network (wavenet), is presented.
The model is verified by field observations and used to investigate the responses of retaining wall and surrounding ground to PED. Results indicate that the maximum wall defection (δhm) and surface settlement (δvm) can all reach centimeter level under common conditions of PED.
The predictions are: (1) the maximum surface subsidence within the mining area is 2.14 m, with the maximum settlement point located in the mid-west area of the coalfield, and (2) the nearest distance from the boundary of the surface movement area to the edge of the dam foundation is 35 m.
The numerical analysis shows that when the ground surface settlement is about 30 mm, which is the allowable settlement in an urban area, the maximum settlement at SF No. 2 on the side close to the tunnel is about 13 mm.
The method We've already covered the importance of pressing your sandwich for maximum surface contact – but what surface is best?
That stone is set on edge for speed and maximum surface area and slapped upward with wet cement.
Indoors, the light-gathering material in the leaf cells turns to offer the maximum surface area to the limited light.
Ground volume loss induces the ground movement and surface settlement.
