土方工程施工方案
一、工程設(shè)計(jì)情況
    1、本工程為高淳縣高級(jí)中學(xué)擴(kuò)建工程的第二標(biāo)段，由高中樓和門(mén)廳二個(gè)部份組成，基礎(chǔ)均為獨(dú)立基礎(chǔ)和條形基礎(chǔ)，地基持力層為②層粉質(zhì)粘土，中等壓縮性，中等強(qiáng)度。
2、工程地質(zhì)情況，根據(jù)工程地質(zhì)勘測(cè)報(bào)告，本場(chǎng)地為中硬場(chǎng)非地，場(chǎng)地類(lèi)別為Ⅱ類(lèi)，場(chǎng)地等級(jí)為三級(jí)。勘測(cè)報(bào)告提供的地質(zhì)構(gòu)造有三層，第一層為素填土和淤質(zhì)填土，以粉質(zhì)粘土為主，非均勻質(zhì)，強(qiáng)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(qiáng)度，第三層，即本工程的地基下臥層，粉質(zhì)粘土，濕，硬塑-堅(jiān)硬，中等壓縮性和中等強(qiáng)度，底板埋深6.5-8.5m。
3、水文地質(zhì)特征，地下水屬孔隙潛水，主要接受大氣降水入滲補(bǔ)給，雙蒸發(fā)方式排泄，地下
Earthwork construction plan
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
