test pile, for the convenience of engineering application, based on experimental results, suggest that optimal the area replacing ratio available formula(1) [8]: when the pile length is determined, the core pile straight size is too large, the cement soil will produce plastic failure, but not give full play to the strength of concrete, reinforced mixing pile has reached the limit bearing capacity.

Therefore, studies of crack initiation location, crack growth path and fracture surface location have important theoretical and engineering significances.
The single crystal blade axis is [001] orientation in engineering.
(b) Modeling specimen fracture surface of rabbet The analyses above show that the theoretical researches carried out by the finite element simulation of crack initiation location, crack growth path and fracture locations of rabbet have a good agreement with experimental results and engineering application.
The fracture occurs along the {-1-11} slip plane. 3) The crack initiates in the upper edge of the rabbet contact area and grows alternately along the slip plane {1-1-1} and {-11-1}. 4) Researches carried out by the finite element simulation of crack initiation location, crack growth path and fracture location of rabbet have a good agreement with experimental results and engineering applications.

- It is thus supposed that it will be reasonable and practical to recommend the application of proven design models (similarly as was mentioned in Appendix J of [3]) which may serve as an effective engineering approach for the assessment of concrete durability performance – e.g. for the quantitative determination of service life and its statistical characteristics.
