从近期几例海堤垮堤分析江苏的海堤工程

Analysis of Seawall Engineering in Jiangsu from Recent Destroyed Seawalls

70年代中期以来,江苏沿海共发生6例海潮毁堤事故,主要原因是:(a)筑堤标准偏低和防护措施不力;(b)不稳定潮滩围后对滩地的治理不够;(c)施工质量差;等等。因此,新围海涂必须慎重选择海岸位置.正确确定堤线,海堤要防潮标准进行设计,并要严格抓好施工质量和搞好潮滩及海堤的防护。

Since the middal of the 1970s, six accidents that sea tides destroyed seawalls have occured in the coastal area in Jingsu Province. The main causes is include: (1) The standards of seawalls are lower and the protection measures are not sufficient; (2) Harnessing the beach is not adequate after the unstable tide beach is enclosed;and (3) The construction quality of engineering is bad, etc. Therefore, the position of the sea beach must be selected conscientiously and the seawall line must be determined correctly when the sea beach is enclosed. The seawall must be designed by the tidal defence standards. We must do best for the construction quality and make a good job of protection of the tide beach and seawalls.
