内容简介
The book introduces technical problems on dam security observation scientifically. For concrete dam， earth rock dam，bank of near dam region， water conveyance structure， and outlet structure， several plans， are resented. For example，observation item optimizing， test point optimizing， reasonable distribution， and facility selection. Moreover， the bookintroduces security observation designs of seven typical concrete dams and earth rock dams. Then， it shows evaluationof above designs. Based on past experience of dam security observation designs， advanced new technology and meansare generated. Of course， it has tight relationship with practical engineering. As a result， based on the principle（practical， reliable， advanced， economic）， design is optimized. Purposes， such as damsecurity observation， gainingprofit， improving technology level of design and construction， could be achieved. The book is available for technicians of water resources and hydropower engineering design，construction，observation， scientific research， operation， management， facility production. Moreover， it could be used for staff ofuniversity as well.

《Dam Safety Monitoring Design》： 3.Middle grade alarrrung conditions activate alertor 2 and 5，the activate conditions are：①when reservoir coming water esceed 2／3 of maximum discharge，activate alertor；②when the monitoring values are obviously bigger than the maximum values in history and keep stepping up，active alertor 5；③a group of monitoring instruments measuring values in key position are all achieve or exceed the maximum values in history，activate alertor 5. 4.High grade alarming conditions activate alertor 3 and 6，the activate conditions are：①when reservoir discharge reach or exceed the maximum designed discharge water level，activate alertor 3；②when reservoir water level is higher than the maximum designed flood water level，activate alertor 3；③when monitoring instruments at all key positions are showing that the dam start to be destroyed，activate alertor 6；④when monitoring instruments at each key positions all exceed the maximum values in history and obviously increase suddenly，activate alertor 6. ……
