摘要
在大连湾海底隧道碎石基床整平施工中,声呐系统扮演着重要的角色,可精准检测碎石垄的铺设质量,但声呐测量精度易受测距的影响,为研究水中不同测距对声呐的影响程度,确定最适合整平船验收的声呐测距范围,利用整平船全抬升式碎石基床验收方式,通过改变水中声呐测距高度来分析整平船声呐不同测距对检测精度的影响程度,从而得出验收时水中声呐的最佳测距范围,为后续管节的碎石基床整平施工及碎石垄验收提供依据。
In the leveling construction of gravel bed of Dalian Bay subsea tunnel,sonar system plays an important role,which can accurately detect the laying quality of gravel bed,but the measurement accuracy of sonar is easily affected by ranging.In order to study the influence degree of different ranging on sonar in water and determine the sonar ranging range that is most suitable for the acceptance of the leveling ship,this paper uses the acceptance method of fully lifted gravel bed of the leveling ship to analyze the influence degree of different ranging degrees of sonar in the leveling ship on the acceptance accuracy by changing the height of sonar ranging in water,so as to obtain the optimal ranging range of sonar in water during the acceptance.The conclusions obtained are used to provide a basis for subsequent gravel bed leveling construction and gravel ridge acceptance of pipe sections.
