对于沿海、江河滩涂吹填砂土造地的火电厂厂址,建设者面临的首要任务是如何克服欠固结的软弱沉陷地基条件进入场地,开展前期的岩土勘探和后续的建(构)筑物施工准备,这就要求对吹填后的软土地基进行预处理,以满足施工机械进场和后续开挖施工对场地稳定的要求.场地预处理的方法很多,涉及经济性、工期要求和处理效果等多方面的因素;如何结合场地条件,论证选取适合的预处理方案,以期达到经济、工期和效果的最优组合,这是每个设计工程师所期盼的.通过某火力发电工程吹砂回填软土地基预处理方案的论证对比,介绍了该工程场地预处理方案的选取方法、要求和结果,对类似工程建设具有参考价值.
For the thermal power plant sites of coastal land and floodplain filled with sand and sand, the builder’s primary task is how to overcome the underconsolidated weak subsoil conditions into the site, carry out pre-geotechnical exploration and subsequent construction Material preparation, which requires pre-treatment of the soft ground after the filling to meet the requirements of construction machinery entering the site and follow-up excavation of the stability of the site.There are many ways of site preparation, involving economic, construction requirements and How to deal with the effect and other factors; how to combine site conditions, demonstrate the appropriate selection of pre-treatment program, in order to achieve the optimal combination of economy, duration and effect, which is designed by each design engineer.With a thermal power project blowing The contrast of the pretreatment scheme for the soft soil foundation of sand backfill is introduced, the selection method, requirement and result of the pretreatment scheme of the project site are introduced, which is of reference value to the similar project construction.
