修建在软土地基上的高桩码头的位移一般由岸坡变形引起,而码头的过大变形往往会使结构开裂,甚至损坏,严重影响结构的安全度。为此,国内外的学者进行了广泛的研究。 本文根据上海某港区龙吴路高桩板梁式码头投产使用后发生过大位移一例(新建码头由于后方堆荷超载,致使码头产生急剧位移,经量测,水平位移为10厘米,挡土墙下沉10厘米,码头沉降不大,叉桩和直桩桩帽向岸侧开裂,裂缝多为水平走向,逐渐向二个侧面延伸,混凝土剥落,钢筋外露,严重
The displacement of the piled wharf built on the soft soil foundation is generally caused by the deformation of the bank. The excessive deformation of the wharf often causes the structure to crack or even be damaged, seriously affecting the safety of the structure. To this end, scholars at home and abroad conducted extensive research. According to a case of excessive displacement after the commencement of the production of the high-pile sheet-girder pier of Longwu Road in Shanghai, the new wharf will have a sharp displacement due to the overload of the rear pile. After measuring, the horizontal displacement will be 10 cm. Wall sinking 10 cm, the pier settlement is not large, fork pile and straight pile cap to the shore side of the crack, the cracks are mostly horizontal, and gradually extended to two sides, concrete spalling, exposed steel, serious
