摘　　要：本文通过实验研究测定了双桩串列时在不规则波和水流共同作用下在不同桩距条件下桩柱所受的正向力与横向力,分析了正向力、横向力及其合力的时域及频域特性,给出了正向力和合力群桩系数随相对桩距和KC数的变化规律,文中还探讨了双桩串列时的合力值及其方向与单桩时的合力值与方向的比较。The in-line and lift forces on bipiles in tandem array induced by both irregular waves and currents were investigated experimentally in this paper. The characteristics in both time and frequency domain of inline, lift and resultant forces as well as spacing parameters are given. A comparison of the magnitude and direction of resultant forces on bipiles is tandem array with the corresponding values for single cylinder is also made.
