(3) Slices method is used to analyze the stabilization of side slope, which includes the following assumptions: Side slope is made of homogeneous materials, and its slip resistance should comply with coulomb’s law; it should be studied as plane problems; shear plane refers to the crown face passing slope toe; For analysis and calculation, only horizontal forces between slices are considered (4)After calculated the safety factor of slope, we can fix the most dangerous slope, and then infer the position of cracks in side slope, so that key solutions can be found(the computation module is shown in the right picture).

However, due to the influence of printing materials and rough steel surface, and jitter or other factors of printing equipment, the printing character is different from the typewritten characters and handwritten characters, making the steel surface printing character recognition be challenging.

In the condition of normal tool wear, the spindle current amplitude Is and feed motor current amplitude If will fit to the following equation: 321 a p aa ss afvkI ∝ , 321 b p bb ff afvkI ∝ (1) where ks and kf are the influence coefficient of tool and workpiece material as well as other factors; ai, bi (i=1, 2, 3) are the influence exponent of cutting parameters.
The parameters of cutting tool are: tool rake γo = 5°, tool clearance α0 = 8°, cutting edge inclination angle λs = -2°, tool cutting edge angle kr =90°, tool minor cutting edge angle kr΄= 12°, tool corner radius rε = 0.3 mm, cutting condition: cutting speed are 20, 25 and 35 (m/min), feed speeds are 25, 30 and 35 (mm/min), cutting depth are 0.35, 0.45, 0.5, 0.55, 0.9 and 1.15(mm), workpiece material is 40Cr alloy steel.

Building and Solution of Finite Element Analysis Model By taking the vehicle and bridge as two separate and independent systems, we respectively build finite element models with the general finite element software ANSYS, and simulate the action of the moving vehicle load on a large-span light bridge built with composite materials with a 1/4 vehicle model, as shown in Fig.1.

Fig.1 The limited water level of reservoir by stage and singleness 1.2 Proposal of Calculating Flood Control Level of Small Reservoirs by Stages In determining flood control level of small reservoirs by stages, the economic profits of increasing flood control level may not able to offset the human and material resources used to change the water level.
Even so, we still need to find a reasonable solution to the contradiction between the full use of water resources and the substantial consumption of human and material resources.
