大亞灣核電基地新建南區籃球場工程重力式毛石擋土墻砌筑.doc

大亞灣核電基地新建南區籃球場工程位于南生活區原消防訓練站，工程場地將占用南面部分山林坡地，場地的平整需朝南面的土坡進行開挖。根據設計圖紙的場地面積要求，按設計建筑場地面積平整場地，需往南面土坡開挖4.1m左右。且經開挖后，南面將形成一面1～4米高差的裸露土坡（如下圖示），長達66米；東面也將形成一段長約30米，高差約2.5米的坡塹。考慮東面、南面邊坡的長期穩定，將在東、南兩面邊坡上各加砌一排毛石重力式擋土墻護坡。東面擋土墻的高度約2.5m，長約30m；南面擋土墻高度走勢沿原土坡走勢，即高度在1～4米之間，長達66m（如下圖示）。現場土質為砂石混合土，根據土質對南面土坡取1：0.35坡度進行放坡，南面土坡需開挖
約705方（包括擋土墻基槽），需回填土方約330；東面地塹回填面積為135，回
Daya Bay Nuclear Power Base New South basketball court project in the Southern District of the original live fire training station, construction site will occupy the southern part of the mountain slope, site preparation required to carry out excavation south side of the slope. According to design drawings of the site area requirements, according to design construction site area leveling the ground and had to go around the south slope excavation of 4.1m. And by excavating the south side of the form 1 to 4 meters poor bare soil (as shown below), up to 66 meters; the east will also form a 30 m long, 2.5 meters in height difference of slope cutting . Consider the east, south slope of the long-term stability, will be in the east, south slope on both sides of a row of the puzzle added rubble retaining wall revetment. The height of the east wall about 2.5m, length 30m; south slope retaining a high degree of movement along the original trend, or a high degree of between 1 to 4 meters, up to 66m (as shown below). On-site soil is sand and gravel mixed soil, soil under the soil on the south slope to take 1:0.35 Slope, south slope excavation required
About 705 parties (including the retaining wall foundation trench), need to backfill earth about 330; eastern graben filling area 135, back
