Construction Management Information System Study On Large Open Caisson

Open caisson is a construction technique, it is develop from ancient digging well. Because of its simple processes, reliable security, suitable for use, the well structural integrity and bearing capacity, open caisson has become to one of the primary construction technique in build deep foundation and underground structure, now, it has been widely used in railway, bridge, municipal affairs, water supply and drainage, and tunnel projects.With the development of monitoring technology, computer technology and Internet technology, the site operation and manage of open caisson has not satisfied with information demand. In order to guarantee the safety of construction period, improve the informational transmission and sharing, it is necessary to study on the information construction technology of open caisson.From two aspects of monitor and management information system, this article expands discussions and studies on the information construction technology of open caisson. The main contents and results are summarized as follows.1. Based on the open caisson submerged mechanical analysis, combined with predecessor research achievement, this article raise the monitor items of construction period, and carry on study and discussion in monitoring methodology, station set, trigger level, analyze and feedback of monitoring data.2. Based on the " Tong Da" office software and the technique of "Apache+ MySQL+PHP", this article develop the Open Caisson Construction Management Information System. This system solve the spot units information released, transmit and exchange, as well as the sharing. It also solves the paperless office.3. Combine with project case, this article analyze the open caisson overall process monitor in construction period, and prove the Open Caisson Construction Management Information System with good stability, safety, applicability.
