| 摘 要： | 结合妈祖经贸园外围海堤工程滑动后的勘察资料,通过地形测量,对海堤的滑动类型进行了判断,并分析了滑动原因。地形测量及监测结果表明,该海堤滑动为沿底层砂棱体表面产生的平移滑动,而非深层圆弧滑动。滑动原因为潮汐作用导致堤体内外产生较大水位差,堤体在内外水位差的推力作用下,沿底层砂棱体表面发生平移滑动。

| Abstract: | Combining with the survey data of the Matsu economic and trade park peripheral seawall after sliding,the slide type of seawall was judged,and the sliding reason was analyzed on the basis of the topographic survey results.Topographic survey results and monitoring results show that the sliding along the bottom of sea sand prism surface is translational slide,but not deep circular sliding.The sliding reason is that the tidal action results in the great water level difference inside and outside of breakwater,then the translational slide of breakwater occurs along the bottom surface of the sand prism under the effect of hydraulic thrust. |
