This paper dealt with the difference and presented a formula for calculating the monitoring indicatrix of external observations of the dam.

The monitoring results of the pore pressure and settlement show that although the three methods are all feasible,the sand bag well method is proposed as the treatment plan in view of the project cost and the consolidation degree.

on the traces of underground water level change of an abutment monitoring hole in the whole processs, a special abutment leakage of an arch dam is discussed.

Applied anatomy observation and measurement of musculocutaneous nerve and the branches;

Traffic stream Three Parameters Integrated Survey Method and Data Processing;

Several kinds of simple,available operating methods of surveying surge water are introduced so as to use them while lack of survey instruments.

Derformation and convergence survey were made on the drift of Qiaohou Salt Mine withthree techniques.

Total 1500 groups of survey data were obtained through the simultaneous observation of two navigational type GPS\'s and three measurement type DGPS\'s at the identical testing point and these data were analyzed,leading to the actual course of the two types of GPS\'s,which can be used to verify whether it is feasible for navigational type GPS as a course indicator.
