| 摘 要： | 针对宁夏银川某基坑工程,以土钉长度、竖向间距、倾角为因素,安全系数为考察参数,设计L25(56)正交试验方案,以及双因素全面试验方案,应用Plaxis岩土工程专用有限元数值模拟分析软件,采用强度折减法,计算分析各因素对土钉支护结构稳定性的作用规律,优化土钉支护参数.研究得出:安全系数随土钉长度的增大而增大,但长度大于临界值后,继续增加对安全系数的提高有限;竖向间距过小或过大,安全系数均减小;倾角增大,土钉较短时安全系数提高,土钉较长时安全系数降低.最优支护参数为土钉长度15 m,竖向间距2.5 m,倾角8°.

| Abstract: | For the reason of need more space using in video capture device and requiring special resource, a network video collection and transmission program is designed based on embedded system. ARMll and embedded Linux are used in the program to build an embedded platform. The MJPG-streamer is transplanted to the platform as a video server, completing image collection, compression and transmission. Users can observe the real-time video images using a web browser remotely. The experimental results show that the method can collect, handle and send video, remote observation of video images in real time, the occupied space is small. |
