| 摘 要： | 通过室内模拟试验,对比声学蚀积测量仪与电阻率探杆测量砂土海床和粉土海床高程的效果。结果显示:砂土形成海水-沉积物界面迅速、稳定,粉土形成的界面缓慢下降后趋于稳定;当悬沙浓度较大,声学蚀积测量仪难以工作,电阻率探杆可判断界面并反映水体悬沙情况;探杆测量砂土海床高程的平均误差为0.20cm,测量粉土海床时为0.25cm;声学蚀积测量仪适于较固结的粉土海床高程监测,平均误差为0.14cm,测量砂土海床的平均误差为0.27cm;电阻率探杆较声学蚀积测量仪适用性更强。

| Abstract: | During the laboratory simulation experiments,two conventional technologies,the electrical resistivity probe and acoustic monitor system,were compared on detecting variable interfaces of sandy seabed and silty seabed.The elevations of water-sediment interface were surveyed and recorded simultaneously.The results indicate that the sandy sediment deposited faster and the water-sediment interface formed by silty soil descended slowly before it turned to be stable.The acoustic system couldn't work in water with ... |
