This paper introduces the method of 3D deformation monitoring of the total station. After the first and the second monitoring, the coordinates of the observation points are calculated by using the principle of coordinate transformation, and the displacement of the monitoring points is obtained. A formula for calculating the displacement accuracy of the monitoring points is derived and given by using the law of error propagation. The results show that the method is feasible. © 2017, Wuhan University. All rights reserved.

Surface precipitation calculation and application is a complex problem. It involves not only how to calculate, and more importantly, a broad range of issues of calculation and results which are both closely integrated with application. It mainly includes the reliability, representativeness and consistency of surface precipitation; the calculation of surface rainfall depth and rainfall amount in general different durations, rainfall area and its corresponding total amount in different durations, specified range and different degrees; the calculation of characteristic index of surface rainfall location, area, rain depth, total amount, and the corresponding shape, mobile, development within rain district or fixed area to analysis surface rainfall characteristics and changes. Taken sediment formation and variation of the midstream of the Yellow River as research objectives, this paper presents the flood control design and flood resource application research with larger flood to satisfy the requirement of engineering hydrological calculations, and briefly describes the surface precipitation calculation and research results. © (2013) Trans Tech Publications, Switzerland.

The earth-rock dam on left bank of the head of DJIPLOHO Hydroelectric Power Station adopts the clay core dam. Due to the tropical oceanic climate which is hot and rainy, the soil of clay core wall has high water content. Through the compaction experiment on site, it chooses suitable dry density, formulates reasonable rolling parameters and finally achieves good construction quality, which ensures the construction progress and meets the requirement of engineering. This accumulates valuable experience for the design and construction of same types engineering. © (2013) Trans Tech Publications, Switzerland.

The auxiliary dam of the upper reservoir of Baoquan pumped storage power station is filled with rock-filled concrete, which accelerates the schedule of construction, shortens the duration, reduces investment, and guarantees the quality of the construction effectively. This is the first application of rock-filled concrete in dam filling in hydraulic engineering, and it develops a new technology of using rock-filled concrete to fill dam, which provides valuable experience in the diversity and rationality of hydraulic engineering construction. © (2013) Trans Tech Publications, Switzerland.

Sound velocity variation is the valid parameter as the token of damage variance. In order to discover the blasting damage cumulative effect and the damage evolutive law of rock mass, sound wave measurement for surrounding rock damage under blasting time after time was carried out at some underground engineering; and the data regression was analyzed at the same time. The corresponding relation between rock mass damage and sound velocity variation under several times blasting was analyzed; and the cumulative expanded models of rock mass blasting damage with the baseline of rock mass sound velocity reducing ratio were founded. Research results show that the correlation coefficient of regression analysis is more than 0.981 6, which illuminate the nonlinear cumulative regression forecast models of rock mass blasting damage founded by test results are correct. The final quantity of rock mass damage is the total of initial damage and blasting damage in the cumulative expanded models of rock mass blasting damage, and where the influences of blasting cumulative damage effect and initial damage are synthetically considered. So the models can reflect the damage degree of rock mass veritably, which are reasonable and feasible.
