In this study, a rainfall runoff process analysis method considering the effect of high-rise buildings was proposed. The proposed method was applied to the Yeoksam urban basin in Seoul. For rainfall-runoff analysis, a shot noise process based model was used to independently analyze the runoff from the wall and roof of a high-rise building. Thus, the Yeoksam urban basin was divided into 155 sub-basins for analysis. It was observed that the peak runoff increased by 22.0% in the 9-2 sub-basin. However, in a sub-basin in which the peak runoff increased by 10.0% or more due to high-rise buildings, there was no case where the increase rate of peak runoff was maintained greater than 5.0% until the next sub-basin outlet. Finally, by deriving the runoff hydrograph for the entire Yeoksam urban basin, it was observed that there was no significant difference in rainfall-runoff process, regardless of whether the building was considered. Therefore, it was concluded that the phenomenon of increase in peak runoff due to high-rise buildings occurs only in sub-basin units.

High Alkali

High alkali aluminosilicate glass batches were prepared by five different raw materials, reaction heat of which in melting process was studied by means of DSC thermal analysis method. The results show that reaction heat of batches in the heating process of 25-1600°C exists a significant difference, and which is among 4396.38 J/g-5311.14 J/g, moreover the least is the batches using petalite, while the most is spodumene. In the whole heating process, 380-800°C is carbonate decomposition stage, which accounts for 42-46% of the total absorbed heat; and 800-1200°C is silicate reaction stage, 40-50%; and 1200-1600°C is glass clarify and homogenization phase , 6%-16%. Therefore, carbonate decomposition and silicate reaction is the main part of batches heat consumption, the optimization scheme for materials has a significant effect on energy saving and emission reduction.

Shot Noise Process

Suppose that pulses arrive according to a Poisson process of rate λ with the duration of each pulse independently chosen from a distribution F having finite mean. Let X(t) be the shot noise process formed by the superposition of these pulses. We consider functionals H(X) of the sample path of X(t). H is said to be L-superadditive if for all functions f and g. For any distribution F for the pulse durations, we define H(F) = EH(X). We prove that if H is L-superadditive and for all convex functions ϕ, then . Various consequences of this result are explored.

With the continuous development of urban construction projects in HebeiProvince, the rise and development of high-rise buildings and undergroundengineering, the design and research of foundation pit support structure has become more and more important. The design of the foundation pit support structure directly affects the settlement and position changes of the building itself and the surrounding stratum. In this paper, the characteristics of foundation pit support are analyzed, and the related theories of finite element analysis method are introduced. Combined with the actual situation of Hebei Province, the finite element analysis method is used to simulate the construction method of foundation pile anchor support structure system. The design was analyzed and studied.
