46、过12t/m2。地 基承载力要求1520t,因此真空预压和堆载预压无法满足本工程的设 计要求。 方案二 抛石积淤法 本工程吹填区吹填厚度在2.03.0m左右,要想上车强夯,需要抛 2.0m厚左右的山石。每平方米增加造价,造价昂贵。 方案三 化学(注浆)加固法 高压旋喷注浆法 2m深的钻孔每孔费用造价也较高;另外对表层无法加固。所以此 法也被弃用。 方案四 轻型井点降水法 高真空击密法处理软土地基一个周期一般在1天至2天,比真空预 压缩短工期接近2/3。经过轻型井点降水法工期短,造价低,相对于化 学法和抛石挤淤法节省造价一半。 经过比选,认为轻型井点降水法。 Pushing ahead, Eas
