Determining the location of infiltration ascender line is a key problem to analyze the 3-D seepage field of the tailing pond. As the location of infiltration ascender line is determined by the actual water edge, the calculation location of saturated surface is lower because of no considering the discharge of the mineral water or the flood. When the location is determined by the direct conversion of dry beach length which is suggested in the standards, the calculation location of saturated surface is higher than the measured value. To get the actual location of saturated surface, a new method is suggested to determine the location of infiltration ascender line, called “the indirect conversion method” in the paper. On the basis of the new method, the numerical simulation is carried out to analyze the 3-D seepage field, and the numerical results are compared with the testing results to prove the rationality of the new method.

In this article, we present the numerical analysis of a Free Standing Riser. The numerical simulation was carried out using a commercial riser analysis software suit. The numerical model’s dimensions were the same of a 1/70 reduced scale model deployed in a previous experiment. The numerical results were compared with experimental results presented in a previous article [1]. Discussion about the model and limitations of the numerical analysis is included.

Numerical simulation of vibro-stone column is taken to simulate the installation of vibro-stone column. A relationship based on test is adopted to calculate the excess pore pressure induced by vibratory energy during the installation of vibro-stone column. A numerical procedure is developed based on the formula and Terzaghi-Renduric consolidation theory. Finally numerical results of composite stone column are compared single stone column.

Based on an Engineering Example which was supported by the stepped soil-nail wall, a numerical analysis model was established by FLAC3D,and the process of the excavation and supporting was simulated, and the numerical results of the soil nails internal force and foundation pit deformation were obtained. The simulated result was consistent with the measured results. It shows that the method of FLAC3D numerical analysis can be used to the numerical analysis of foundation pit excavation and supporting, and it will provide the basis for the design and construction of practice project.

Good Agreement

In the present study, the synthetic signals from the combo tube are simulated by using commercial electromagnetic numerical analysis software which has been developed based on a volume integral method. A comparison of the simulated signals to the experiments is made for the verification of accuracy, and then evaluation of five deliberated single circumferential indication signals is performed to explore a possibility of using a numerical simulation as a practical calibration tool. The good agreement between the evaluation results for two cases (calibration done by experiments and calibration made by simulation) demonstrates such a high possibility.

For the precise hole surface, the burr severely affects products’ performance. Considering the specific conditions of the precise hole surface finishing, a new method of two-phase compulsive circulation flows finishing is brought up. Nozzle number, nozzle position, liquid flow, etc. are main factors, which would directly influence finishing effect and efficiency. Affecting rules of main factors are studied by experiments and numerical simulation, which provide basis for thorough research.

Peak Value

The current researches on bolt length are rarely concerned with self-bearing characteristics of anchorage surrounding rock，its stress response is seldom used to analyze the bolt effective length. Tangential stress σθ of surrounding rock is sensitive to mechanical variation of surrounding rock plastic failure fields. When surrounding rock bolted, the distribution curve of σθ presents internal and external peak values from the surface rock to the deep rock, which is verified by numerical simulation. Internal peak value of σθ curve increases with the bolt length, which means the bearing capacity of surrounding rock in plastic failure division is improved, correspondingly, external peak value decreases which shows the supporting behavior of the deep rock is weakened. The results of numerical simulations prove that there exists an effective value of bolt length. If bolt length beyond it, the bearing capacity of anchorage surrounding rock cannot be improved obviously.
