“…Drag anchors can be used as foundations in the mooring system [1], as shown in Figure 1. In general, the size and the shape of drag anchors influence the loading capacity and the capacity to penetrate into the soil, respectively [2]. It is very important to fully understand the loading capacity of drag anchors; therefore, some scholars have conducted the research on the loading capacity, such as O'Neill et al [3], Merifield et al [4], Merifield and Sloan [5], Song et al [6], Aubeny and Chi [7], Tian et al [8], Han et al [9], Cheng et al [10], Peccin da Silva et al [11], and so on.…”
