Pile-soil interaction simulate of different inclined pile bulkheads under back filling

Hydraulic filling was frequently used for forming land in port construction. For example, the storage yard forming in deep water port may need high filling, so the bulkhead structure of wharf would passive bear the soil pressure produced by high filling. Inclined pile with sheet piles bulkhead was considered in a deep water port, the design of bulkhead structure has two types of scheme, one of them is back-vertical pile scheme and the other is front-vertical pile scheme. This paper used finite element method to simulate the high filling construction process behind the bulkhead, and the structures' deformation and earth pressure of two type of bulkheads have been analyzed, and some rules about the inclined pile bulkhead structure have been concluded. The conclusions can be used as reference for similar projects in future.
