Fig.8 Failure features for the datum beam Fig.9 Failure features for the strengthened beam Crack-resistance analysis.
From Table 5, it is knowable that, compared with D2, the ultimate shear strength of B16, B17, B18 increases greatly, with amplitude be from 14.29% to 31.43%.Reinforcement ratio of B2, B3, B4, B5, is respectively 1.0%, 1.5%, 2.0%, 2.7%.Test data shows that, the ultimate capacity of strengthened beams is improved as it increases.
As for stirrup ratios, Data shows that, the ultimate capacity rises with it increasing, and B10, B12 is improved respectively by 12.5%, 10.0% compared with B11.but B12 is lower than B10, which is caused by the manufacture of production and test.
Data shows that, the ultimate capacity increases with it decreasing.
Secondly, with the reduction of the spacing of wire rope, the diagonal crack resistance increases.

Statistical analyses of observed ground motion data could help recognize the mechanism of demolition vibration, and develop efficient measures to reduce its influences[3,4].
Referring to the Sadov's Formula of blasting vibration and depend on observed data of chimney blasting demolition, several similar semi-theoretical formulas with empirical coefficients were developed[5-8] in order to predict the ground motion with vertical PGV.
The hollow triangles in the left graph denote unreasonable data omitted during curve fitting.
This smaller indicated that the vibration decreasing measures, including cross folding collapse style, damping ditches and vibration decreasing dams, had a positive effect on vibration reduction of the building collapse source.
So, more data are needed to find the determinant for the decaying coefficient.

In the data processing, on the basis of the effect of two kinds of single component water reducer, using the proportional weighting rules and the interpolation method, a theoretical effect curve characterizing effect of "1 + 1 = 2 " was calculated, which was compared with the effect curve of compound water reducer measured in test.
From those figures, it can be seen that, in this ratio, the measured effect curve of compound water reducer was basically below the theoretical effect curve, which indicated that the water reduction rate reduced and only effect of "1 +1 <2 " could be achieved after compounding.
As can be seen from Table 1, when single water reducer was added, for POLYETHER or CLS, the adsorption amount increased with the growth in dosage; At the same dosage, the adsorption amount of POLYETHER was much smaller than the adsorption amount of CLS, but the fluidity data shown that the fluidity of POLYETHER was much larger than the fluidity of CLS.
Combining the data of cement paste fluidity, it can be seen that the greater the increased amplitude of the adsorption amount of POLYETHER in the compound water reducer, the worse the compounding effect of the compound water reducer.
Combined with the data of cement paste fluidity, the greater the increased amplitude of the adsorption amount of POLYETHER in the compound water reducer, the worse the compounding effect of the compound water reducer.

Formulation cleaning performances: Based on pareto analysis of the DOE response Light Particle Density (LPD) reduction was a function of PCMP concentration and hydrodynamic/ mechanical processes.
Low ionic strength promotes electrostatic repulsion on silica (ZP), consistent with experimental data[10].
Experimental data confirmed the higher cleaning efficiency of organic residues at higher PCMP concentration-A (Fig-4).
Electrical data An increase in reliability as measured by Time dependant dielectric breakdown (TDDB) was seen TDDB measurements on 150nm and 90 nm devices confirmed the high residue and particle cleaning performance of the neutral PCMP blend (Figure 8).

The sediment in part of the urban drainage pipes is too much, and some are even accounted for more than 50% of the diameter of the pipe; What’s worse, those sediment in the pipes will cause secondary pollution; most pipelines are reinforced concrete, and the inner wall is rough, which would bring great resistance to water flow, resulting in an increase in sediment in the drainage channels and the reduction of the cross-section of the drainage channels. 2.6 The poor ground water seepage The accelerating of urbanization, the wide using of concrete in all types of buildings and roads and large area indurations of ground surface of cities, cause the impervious urban ground water seepage in the vast majority of area, affecting the ability of urban ground water seepage, indirectly adding the burden of the urban drainage system, especially in heavy rain season, the city is prone to flooding.
By optimizing the selection ,conclude the city which is able to calculate the drainage system traffic control points, and then through the sensor ,collect the data of those points traffic and the flow of velocity , and transmit the data to a central computer; then get the best program of drainage system scheduling by computer-aided calculation, and then through the data transmission equipment weir, transmit the instructions from Center computer to gate valves, pumps and other equipment, so as to achieve the purposes of implementing scheduling of the surplus in the pipeline flow.
The third is to strengthen the information construction of the drainage system, which Includes control point sensor, the data transmission device, the flow regulating device controllers, and central computer. 4 Conclusion To improve the city's drainage capacity is a complex systems engineering, so we need to take a systematic ideas to solve the problem.
