This paper establishes mathematics model of controllable anti-skid device system. A simulation and analyze is introduced in SIMULINK of Matlab to study the constant deceleration braking of braking system. Through computer simulation, the dynamic response of the system which using PID control and fuzzy control is inspected, and the advantages and disadvantages are pointed out. A parallel-type fuzzy PID controller is built, which shows that the fuzzy PID controller is superior to PID control and fuzzy control. ©2010 IEEE.

A foundation pit located within the safety protection control line of Wuhan Yangtze River tunnel is taken as an example. The internal forces, displacements and other technical indices of single circular strut and concentric circular strut are comparatively analyzed. The calculated results show that the concentric circular strut can effectively share the axial forces. It has more reasonable structural stress, higher overall stability and supporting stiffness. It can effectively control the adverse influences of Wuhan Yangtze River tunnel and the surrounding building during the excavation of the foundation pit. Great economic and social benefits are achieved.

An excavation located in 1st terrace near Yangtze River in Wuhan City is taken as an example. The design concept of large scale being divided into small, segment design, severity and combined bracing is put forward. According to engineering geological conditions and construction deployment, different retaining structures such as pile-strut, double-row piles and reinforcement in passive zone are combined reasonably both in the plane and space, respectively. It achieves the convenience of earthwork and basement construction under the premise of safety and economy of supporting structures and surrounding environment. It may provide a good reference for other similar projects.
