土方工程施工方案
一、工程設計情況
    1、本工程為高淳縣高級中學擴建工程的第二標段，由高中樓和門廳二個部份組成，基礎均為獨立基礎和條形基礎，地基持力層為②層粉質粘土，中等壓縮性，中等強度。
2、工程地質情況，根據工程地質勘測報告，本場地為中硬場非地，場地類別為Ⅱ類，場地等級為三級。勘測報告提供的地質構造有三層，第一層為素填土和淤質填土，以粉質粘土為主，非均勻質，強度低，該層底板埋在0.5-2.8m。第二層為本工程的持力層，厚度為1.0-3.7m，中等壓縮性和中等強度，第三層，即本工程的地基下臥層，粉質粘土，濕，硬塑-堅硬，中等壓縮性和中等強度，底板埋深6.5-8.5m。
3、水文地質特征，地下水屬孔隙潛水，主要接受大氣降水入滲補給，雙蒸發方式排泄，地下

First, engineering design situation
    1, this works for Gaochun County High School expansion project's second sections, from the high school building and the hall composed of two parts, based on an independent basis and are strip foundation, foundation bearing stratum layer of silty clay to ②, Medium compression, moderate intensity.
2, engineering geology, according to engineering geology report, the site is in the field of non-hard, the site category Ⅱ, site grade 3. Survey report of geological structure has three, the first layer is a prime quality of fill and silt fill, to silty clay-based, non-uniform quality, low intensity, the bottom layer buried 0.5-2.8m. The second layer-based engineering support layer, thickness 1.0-3.7m, medium and moderate compression, the third layer, that is the foundation of this project under the substratum, silty clay, wet, hard plastic - hard, medium compressibility and moderate intensity, bottom depth of 6.5-8.5m.
3, hydrogeological characteristics and groundwater is phreatic, meteoric recharge of the main receiving double evaporation drainage, underground
