渠道高边坡的稳定直接影响到渠道的安全，为了解边坡变形情况并对边坡在施工期、运行期可能产生的滑坡进行预警，对边坡进行全面的安全监测设计是十分必要的。以南水北调中线某段渠道高边坡为例，开展了安全监测工作。监测项目主要有位移、边坡变形、地下水位监测，根据“互相验证、临时与长期结合、经济合理”的原则，布置水平位移标点、多点位移计、测斜管、渗压计等监测仪器，保证施工期和运行期及时、准确地掌握边坡的变形和地下水位等信息，为评价工程安全、及时采取相应措施提供可靠依据。对已施工完成的边坡安全监测资料的分析表明，边坡处于稳定状态。
渠道高邊坡的穩定直接影響到渠道的安全，為瞭解邊坡變形情況併對邊坡在施工期、運行期可能產生的滑坡進行預警，對邊坡進行全麵的安全鑑測設計是十分必要的。以南水北調中線某段渠道高邊坡為例，開展瞭安全鑑測工作。鑑測項目主要有位移、邊坡變形、地下水位鑑測，根據“互相驗證、臨時與長期結閤、經濟閤理”的原則，佈置水平位移標點、多點位移計、測斜管、滲壓計等鑑測儀器，保證施工期和運行期及時、準確地掌握邊坡的變形和地下水位等信息，為評價工程安全、及時採取相應措施提供可靠依據。對已施工完成的邊坡安全鑑測資料的分析錶明，邊坡處于穩定狀態。

The stability of high canal slope directly influences the safe operation of canal. In order to master slope deformation condition and early warm the possible landslide, it is necessary to carry out overall monitoring for slope. Taking a high canal slope of Middle Route Project of South to North Water Diversion as a case, the safety monitoring was conducted and the monito-ring contents include displacement, slope deformation, underground water level. According to the principles of"mutual verifica-tion, combination of long-term and short-term, economic and reasonable", the monitoring devices of horizontal displacement mark, multi-points displacement meter, inclinometer, osmometer etc. were arranged to monitor the slope deformation and un-derground water timely and accurately.
