1. Meanwhile, some pile driving works are already done.

2. The results in - situ measurement of pile driving in the construction of a power plant are presented.

3. In this paper, a photoelastic simulating method of pile driving is presented.

4. Hydraulic pile hammer is one of the pile driving machines that drive prefabricated piles into the ground in the construction of pile foundation such as construction, bridge, dock, etc.

5. According to the analysis of the pile driving the estimating method of pore water pressure of soil in surrounded pile is obtained under the computing assumption condition.

6. The attenuation characteristics of ground vibrations caused by pile driving were proposed.

7. The effect on environment pile driving is received more and more emphases by civil engineers.

8. The effect on environment during pile driving is received more and more emphases by civil engineer.

9. The attenuation characteristics of ground vibration caused by pile driving were proposed.

10. The result of pile driving proves that the measure is feasible and may serve as a reference for pile driving construction of similar projects.

11. It is one of pile driving to predict more accurately driveability analysis.

12. In this paper the problem of pile driving is qualitatively analyzed, some conclusions about soil displacement are obtained.

13. The method of dynamical measurement which was applied to analysis of pile driving is extended to test and measurement on the stiffness and strength of vertical joints between diaphragm walls.

14. A method based on the stress-wave theory to estimate the static resistance at pile toe during pile driving has been developed.

15. In view of this, the thesis advanced a new "bring to an end" criterion in vibratory piling process, which provide a theoretical basis for ending pile driving.

16. The position of hard formation and pile broken during pile driving also conformed to this rule.

17. The electro-hydraulic system will curtail action cycle(http:///pile driving.html), improve the quality of pile driving and promote efficiency.

18. The main causes of breakage were concrete tube pile instability of foundation pit or failure of its bracing, soil squeeze due to pile driving, incorrect excavation and incorrect heap of soil.

19. Great soil squeezing pressure and excess pore water pressure were arisen during large-area pile driving engineering due to thick soft soil layer.

20. Example showed that by using the optimum combination of parameters obtained by the program the driving efficiency in-creased obviously and quality of the pile driving can also be ensured.

21. The deflection of precast piles and excavation problems induced by pile driving are introduced through an engineering case of pile foundation treatment of a power plant.
