However, only the vertical auto-correlation structure can be effectively identified because CPTs are conventionally conducted in the vertical direction. The identification of the horizontal auto-correlation structure cannot be effectively achieved by conventional CPTs. In the literature, very limited horizontal CPTs were conducted by researchers, but they are seldom conducted in practice probably due to its high cost and technical difficulty. Inclined CPTs are more feasible than horizontal CPTs. The purpose of the current paper is to investigate the possibility of adopting inclined CPTs to identify the horizontal auto-correlation structure of soil variability by numerical examples. A two-dimensional random field is used to generate synthetic CPTs data. The feasibility of identifying the horizontal auto-correlation parameters is then investigated by analyzing the synthetic data from inclined CPTs. The preliminary results obtained by the current paper may be useful for our future work in this line of research. |
