摘要：上海地区降雨量大，种植屋面结构荷载大，屋面雨水无法迅速排走，严重影响植物的正常生长。如果存在渗漏等情况，会给经营者带来经济损失，严重者还会因为负荷增加导致结构坍塌，从而造成重大人身和财产损失。通过 从设计、材料选择、施工节点等方面介绍种植屋面虹吸雨排系统的关点，保证虹吸雨排的施工量和应用效果，为目提供指导和借鉴。 关键词：虹吸雨排；商业种植屋面

rief Analysis on Three-year Action Implementation Plan for Improving Quality and Efficiency of Urban Wastewater LUO Gang,HUA Zheng,LI Mei,QI Leiting,SHE Bucun(N3) Abstract：Through the assessment and analysis on the current situation of wastewater treatment plants (WWTPs),pumping stations,main pipe network,drainage areas up to standard,informatization and management mode in Wuxi,there are problems of the low influent concentration and high operation load in some WWTPs,the old equipment without the relative unification standard and with high load operation in sewage pumping stations,the high operating wat
er level,and incomplete rainwater and sewage separation in the sewage pipeline network,and the poor scheduling and functions and structural defects in the main pipeline network in Wuxi.The6+1work measures are formulated for the implementation plan of three-year action to improve the quality and efficiency of urban wastewater in Wuxi,such as to construct the drainage areas up to standard,completely to investigate and repair the pipeline networks,to construct the sewage pipeline network,to construct the standardized pumping stations,to upgrade the standard and expend the capacity of WWTPs,and to build the informatization engineering and management mechanism.After three years of efforts to improve the quality and efficiency of urban wastewater treatment systematically,three"two-high and one-low"changes of high influent concentration,high effluent standard and low pipe network water level of the wastewater treatment in Wuxi are realized.

Application of Siphon Rainwater Drainage System in Planted Roof of .
.................... .........................................................................................................................................................................HOU Yonghui(92) Abstract：The roof rainwater is hard to quickly discharge because of heavy rainfall in Shanghai and large
load of planted roof structure,which seriously affects the normal growth of plants.The leakage and other conditions if existing will bring great economic losses to the operators,and if seriously will lead to the structural collapse because of the increase in load so as to cause the heavy personal and property losses.
The key technical points of siphon rainwater drainage system for planted roof are introduced from the aspects of design,material selection and construction nodes,and the construction quality and application effect of siphon rainwater drainage are ensured,which provide the guidance and reference for the follow-up similar projects.

Design of Waterfront Platform Based on Finite .WANG Lulu(99) Abstract：The numerical simulation of the waterfront platform is carried out by using ROBOT to verify the applicability of ROBOT to practical engineering calculation.Through a relatively complete load combination calculation and analysis,the research shows that it is feasible to analyze the mechanical performance of the high pile waterfront platform structure by using the ROBOT numerical simulation method,and the calculation results are true and reliable,which can be used in the actual engineering design.The maximum positive and negative bending moments of the waterfront platform are on the crossbeam generated by the ship collision force.The maximum axial force of the pile foundation of the waterfront platform appears in th
e sixth row pile of the second bent frame.The bending moment of pile foundation in rows1to4is small,and in rows5and6is large.

Key Technique of Long-distance Pipe Jacking Horizontal WANG Hao(102) Abstract：In order to solve the problem that the existing pipe jacking horizontal survey method is not applicable for the pipe jacking machine in long-distance tunneling,the precision demand proportional to the tunnel distance of pipe jacking machine is taken as the starting point.According to the different range precision demands,the appropriate horizontal control survey method is found.All kinds of pipe jacking horizontal control survey techniques are organically combined with the single-station trajectory oriented long-distance pipe jacking guidance system.The working efficiency can be improved and the working intensity can be reduced at the same time to meet the precision demands.By using this method,two
2.67-km pipe jacking tunnels of Suzhou Urban Area Second Water Source一Yangcheng Lake Diversion
Project are successfully completed.
