21、有限責(zé)任公司， 設(shè)計單位為中煤科工集團(tuán)重慶設(shè)計研究院有限公司，地勘單位為中鐵工程設(shè)計院有限公司，監(jiān)理單位為重慶中泰工程監(jiān)理有限公司， 施工單位為重慶市軒園建筑工程有限公司。本次施工擬建建筑物為洋房部分為7+1 層、商業(yè)三層、車庫一層，地基基礎(chǔ)采用強夯法處理，即兩遍點夯加兩遍滿夯進(jìn)行處理，強夯面積約18000多nf。2、場地地質(zhì)條件：場內(nèi)地層主要有第四系全新人工素填土、沖洪積粉質(zhì)粘土以及碎石土，下伏基巖為三疊系中統(tǒng)巴東組泥巖和泥灰?guī)r。二、地基基礎(chǔ)局部換填處理前提情況2013年12月6日，在對18#商業(yè)北側(cè)80米X 32米范圍進(jìn)行第 二遍點夯，夯擊10個點位后發(fā)現(xiàn)：按照3000KN.m夯能，夯4-

22、5擊， 未達(dá)到收錘標(biāo)準(zhǔn)時，夯坑深度都在2.6m-3m以上，且收錘困難，夯坑周圍隆起較大，最高至 0.8m。隨后，在夯坑中填筑中風(fēng)化填料后繼 續(xù)夯擊，6擊后，夯坑深1.8m,周圍隆起0.4m,其夯擊數(shù)與夯沉量 仍然達(dá)不到設(shè)計要求和收錘標(biāo)準(zhǔn)。賡即，我方通知業(yè)主、地勘、監(jiān)理 單位代表現(xiàn)場查看。經(jīng)業(yè)主單位林世德、林仕榮、嚴(yán)工，地勘單位薛相國，監(jiān)理單位鄒方軍及施工單位技術(shù)負(fù)責(zé)人現(xiàn)場查看后，決定用挖機向下深挖，以探查下層的土質(zhì)情況。挖至高程174.6 （深3.5m）后觀察發(fā)現(xiàn)：其土呈軟泥狀，含水率大，有明顯水浸泡的特性。初步分析，本施工區(qū)域緊鄰朱衣河北側(cè)，受三峽水庫175 米水位影響，長江水滲透后長時間浸

24、高程及范圍測量用水準(zhǔn)儀測出需換填部位的地貌高程，用全站儀測出換填范圍邊線坐標(biāo)，為最終確定土石方換填的工程量作依據(jù)。4、換填施工機械準(zhǔn)備本工程地基基礎(chǔ)強夯工期緊，且土石方換填工程量較大，為不影響原施工計劃，土石方換填需240挖掘機一臺，推土機一臺，20T雙 橋運輸車5輛（外運，填料運輸車輛數(shù)臺），18T壓路機一臺。四、土石方換填施工步驟工藝流程：開挖位置的界定（撒白灰線）、原地貌收方-土方開 挖、外運一檢查軟土層是否挖完一確認(rèn)深度（范圍）并收方一塊石土 回填、分層碾壓一填至原地貌高程后清理、找平一驗收。1、按照初步確定的換填范圍，開挖一段后，根據(jù)現(xiàn)場的土質(zhì)情況，請地勘單位、建設(shè)單位、監(jiān)理單位代表

25、現(xiàn)場確定具體開挖深度及范圍。2、確定開挖順序：因業(yè)主指定的棄土場位于施工現(xiàn)場西北方向（約1Km） ，現(xiàn)場開挖時可由西向東進(jìn)行挖運。3、土方開挖：現(xiàn)場配備一臺240 型挖掘機開挖、裝土，利用自卸車運至業(yè)主指定的棄土場，棄土場用推土機堆高及修路。4、現(xiàn)場檢查：挖至要求的深度及范圍后，邀請建設(shè)單位、地勘單位、監(jiān)理單位代表，對已開挖的土層進(jìn)行檢查（設(shè)計單位可傳影像資料） 。確認(rèn)后，收測深度和范圍。5、塊石土換填：（1）用挖掘機或推土機將坑底整平，用18T壓路機碾壓。（ 2）換填：換填料必須滿足設(shè)計要求。換填塊石土運至坑內(nèi)，用推土機推平，然后用18T壓路機分層碾壓，分層厚度為50cmi換填碾壓密實度參照

26、原回填碾壓后的密實度。（3）填料質(zhì)量要求：填料采用中等風(fēng)化石料，填料中塊石粒徑r be.
