路基不均匀沉降的控制措施对于先天设计不足的,通过实地调查后,上报监理工程师及指挥部,进行设计变更,按设计变更要求进行处理。路堤填筑前做好原地面处理。填筑路堤时首先进行原地面处理。当路堤填筑高度小于1.0m时,将路基范围内的树根、杂草全部挖除。若基底的表层土系腐殖土,则须用挖掘机或人工将其表层土清除换填,厚度视具体情况而定,并按规定进行压实。路堤通过耕地时,路堤填筑施工前预先清除表
Subgrade uneven subsidence control measures For the inherent design deficiencies, after the field survey, report to the supervisory engineers and headquarters, the design changes, according to the design change requirements for processing. Embankment prior to filling the original ground handling. Filling the embankment when the first ground treatment. When embankment filling height less than 1.0m, the embankment within the roots, weeds were all excavated. If the topsoil of the substrate is humus soil, it must be removed by excavator or artificial surface soil replacement, thickness as the case may be, and according to the provisions of compaction. When the embankment passes through the cultivated land, the table is cleared before embankment construction
