摘要 北京环球影城园区基坑大量土方开挖的基本办法是向附近土场消纳。但180 m3的土犹如20多个足球场上堆起近9 m高的土,如此大的土方量,运输和消纳成本相对较高,运输过程中也会造成撒落。为了减少土方外运成本和环保无污染再利用,减少掺料添加,环球影城园区的萧太后河南街道路工程采用原有素土回填路床,项目大部分属于填方工程,且填方较高。因此采用道路工程素土路床回填技术对整体质量控制有很大的提升。 The basic approach for mass excavation of the foundation pit in the Universal Studio of Beijing was to transfer soil to nearby soil yards.However,soil of 180 m3 is equivalent to 9m mounds on more than 20 football fields.Costs of large-scale earthworks,transportation and transfer are relatively high,and soil may be scattered during transportation.In order to reduce the cost of soil transportation,make use of soil in a pollution-free manner,and reduce the dosage of additives,the roadbed was backfilled with original plain soil in Xiaotaihou South Street in the Universal Studios.The project mainly involved high-level filling works.Therefore,roadbed backfilling with plain soil in road engineering will greatly improve the overall quality control.
