traffic signal light pole is the important part of traffic engineering, traffic lights is way of structural support. To make the traffic lights in all kinds of natural environment, able to play a fixed uninterrupted traffic signal function, in structure design, must fully consider the load bearing mechanical strength, stiffness and stability, and at the same time, traffic lights as part of the road traffic, in structural design, also consider the highway beautification. Role, under the possible conditions led street lamp standards, as far as possible, make its structure grand, spectacular, and in harmony with the intersection building environment. Commonly used calculation method of the traffic signal light pole has two kinds: one kind is applied the principle of structural mechanics and material mechanics will light structure is simplified to bar system, limit state design method is adopted to improve the calculation; Another is to use the approximate calculation method of calculation of the finite element method. Though finite element method using computer calculation more accurate, when in actual use because of the limit state method can give enough accurate conclusion, and calculation method is simple and easy to understand, so is widely used. The upper structure of traffic signal lamp lever generally adopts steel structure, adopt based on the theory of probability limit state design method, the bearing capacity limit state and normal use limit state design, concrete foundation is used for the lower foundation, using the theory of foundation engineering design.
