城市快速干道综合排水系统现场测试方法

结合上海市外环线（浦东段）二期工程综合排水试验段，首次系统地研究了城市快速干道综合排水系统中路表排水、路基排水（盲沟排水流量、盲沟节点压力及盲沟水力坡降）和路面结构内部排水的现场测试方法、数据采集系统等，并将采集的数据通过调制解调器远程传送，随时获取实测数据，进行分析研究．现场试验结果表明：该系统测试方法合理、手段先进、运行稳定、数据采集准确可靠．

New Field Test Methods on Synthetic Drainage System of City Expressway

During the construction of the secondary project of Shanghai outer-ring road(Pudong section),a synthetic drainage system was set up for experiment.The new methods of field test and data collection upon surface drainage,subgrade drainage(water discharge of blind drainage,node pressure of roadbed,rainfall distribution of blind drain) and inner drainage of roadbed construction with the city expressway were systematically studied for the first time in China.A set of automatic test instruments that monitor synthetic drainage working were installed on the spot,and then the real-time data were telecommunicated via modem for real-time monitoring and control.The field tests indicate that the methods are reasonable,the instruments are advanced,the operation is steady,and the data collection is accurate and reliable.
