天津站地下人防工程位于天津站前解放桥广场东侧,场地表面为厚约2.5m杂填土,2.5m以下为轻亚粘土,静止地下水位在自然地面以下2.7～3.0m处,雨季最高水位-1.5m,土饱和容重18.8～19.5kN/m～3,内聚力c=16～25kPa,内摩擦角φ=20°～25°(降水后)。该工程总建筑面积为5813.76m～2,中间多用厅部分深9.75m,两侧深8.75m,东西长67m,南北宽37.6m,东西两侧留有过街通道口,南侧有两个通向花坛的安全出口通道。建筑平面为带双翼的矩形,地坪至基础底板结构下皮最大挖深10.27m。平面形式见图1。
The underground air defense project at Tianjin Station is located at the east side of Jiefangqiao Square in front of Tianjin Railway Station. The surface of the site is about 2.5m thick and miscellaneous fill, 2.5m below is light sub-clay, static groundwater level is 2.7~3.0m below the natural ground, and the highest water level in the rainy season. -1.5m, saturated soil bulk density 18.8 to 19.5kN/m~3, cohesion c=16~25kPa, internal friction angle φ=20° to 25° (after precipitation). The total construction area of the project is 5,813.76m~2. The central multi-purpose hall is 9.75m deep, 8.75m deep on both sides, 67m long from east to west, and 37.6m wide from north to south. There are crossing passages on the east and west sides, and there are two routes to the south. Safety exit passage for flower beds. The plane of the building is a rectangle with wings, and the maximum depth of digging of the undersurface of the floor to the base floor structure is 10.27m. The plane format is shown in Figure 1.
