大连振兴公路,长11.49km,是沟通大连市区和大连经济技术开发区的一条主要干道,为一级公路,路面宽26m,公路跨越甜水套子和红土堆子两处海湾,跨海路堤全长3191.81m,路堤中心填高6～19m,堤身长年受潮汐影响。设计水位2.8m(百年一遇高程),设计高潮位1.68m,设计高潮位时最大浸水深4.48m,H_B％=2.4～3.01m。两处路堤的基底地层:甜水套子海湾表层为粉细砂间夹淤泥质亚粘土及亚粘土和亚砂土、圆砾;红土堆子海湾表层为淤泥质亚粘土及圆砾;以下均为粘土和石灰岩,红土堆子石灰岩中有小溶洞零星分布。海堤设计采用了下部填石,上部填碎石土的斜坡堤断面见图1。有关海堤的坡面防护,
Dalian Zhenxing Highway, with a length of 11.49km, is a major trunk road connecting Dalian urban area and Dalian Economic and Technological Development Zone. It is a Grade I highway with a width of 26m. The highway crosses the full length of the sweetwater cover and the red clay pile in two bays and the sea embankment 3191.81m, embankment center filled 6 ~ 19m, the dike affected by the tides for many years. The designed water level is 2.8m (elevation at one hundred years), the designed high tide level is 1.68m, and the maximum immersion depth at design high tide level is 4.48m and H_B% = 2.4 ~ 3.01m. The basement of the two embankments: the surface of the sweetwater shoal bay silt mud between the fine sand silt loam and sub-clay and sub-sand, round boulders; laterite dikes Bay surface silt clay and round gravel; the following are clay And limestone, laterite karst limestone cave scattered distribution. The lower part of the seawall is designed with a lower part of rock fill. The slope protection of the seawall,
