摘要
随着社会的发展,水生态修复已经成为保护环境主要建设内容,在满足环保要求的前提下,通过实施水库、湖泊整治清淤疏浚工程,减少污染底泥对水体水质的影响是具有重要社会意义的。在清淤疏浚工程中,水域淤泥厚度的探测是非常关键的,传统上对于淤泥厚度的探测大多是利用钻机和人力探杆取样,从而对淤泥进行层位划分,这些方法工作效率低,覆盖范围窄。本次研究利用了一种新型的多模式声呐系统,将浅地层剖面法和侧扫声呐法相结合,两者同时采集数据,浅地层剖面法探测厚度,侧扫声呐法确定范围,这样提高了水域淤泥探测的精度,有效地指导了清淤疏浚工程的进行。最后通过该声呐系统在云溪水库中的成功应用,证明了多模式声呐技术是一种高效的探测淤泥的技术手段。
With the development of the society,water ecological restoration has become a major concern before enbarking any large infrastructure constructions.To meet the requirements of environmental protection,strictly monitoring the implementation of the reservoirs,lakes dredging project,reducing pollution is the prerequisite of sediment on water quality.In dredging engineering,water sludge thickness detection is very crucial,traditionally for sludge thickness detection,mostly using the drill rod and manpower,and the silt layer division,with which methods,work efficiency is low,coverage narrow.In this paper,a new type of multi-mode sonar system,the shallow stratum profile method and side scan sonar method conbined,both collect data at the same time,with the shallow stratum profile method detecting the thickness of side scan sonar method to determine the range to improve the water silt detection precision and the effective guidance of the dredging project.Finally,the sonar system in the successful application of Yunxi reservoir proved that the model sonar technology is more efficient in the detection of silt.
