Sheet pile wharf has been widely used in coastal and inland areas for its advantages such as struc-ture simplicity, constructing convenience and suitability of complicated geological conditions etc. Conventional de-sign methods assume that earth pressure in front of and behind a sheet pile wall achieve the passive and active criti-cal states, respectively. However, the lateral deformation and displacement of the entire wall are restricted to a vari-able extent due to the combined effects of soil and anchor structures during the construction and service periods. Hence, the actual earth pressure is not in the critical state which could lead to conservative project design with waste of cost or rash one with hidden danger. Therefore, many researchers studied the influence of lateral deforma-tion and displacement on the earth pressure in front of and behind a sheet pile wall, and many results were obtained. In this paper, the state of the influence of lateral deformation of soil on earth pressure coefficient and displacement of the sheet pile wall on earth pressure were reviewed to summarize the main conclusions. Finally, some suggestions on the direction of future research were presented.%板桩码头具有结构简单、施工方便、对复杂的地质条件适应性强等诸多优点,被广泛应用于沿海和内陆地区.常规的设计方法假定作用在板桩墙前后的土压力达到主动与被动极限状态,然而在板桩墙的施工和使用过程中,由于受到土体与锚碇结构的共同作用,整个墙体的侧向变形和位移会受到不同程度的限制,所以实际的土压力并不处于极限状态,这可能导致工程设计过于保守而造成浪费或过于轻率而产生安全隐患.因此,众多学者围绕侧向变位对板桩墙前后土压力的影响开展了卓有成效的研究.文中对土体侧向变形对土压力系数的影响和板桩墙变位对土压力的影响进行了综述和归纳,明确了板桩墙所受土压力的变化规律,并探讨了后续需进一步研究的问题.
