Combining the engineering examples,some methods such as drilling,excavating test pit,surveying the existent pit,and engineering analogism to describe the veracious gravel stratum are offered,which provide the basis for the design and construction of the tunnel and the retaining piles.
本文结合工程实践,采用钻探法、探井法、既有基坑调查法及工程类比法等多种手段进行综合分析,以提供更为接近实际的含大粒径卵砾石地层描述,为地铁盾构隧道及基坑围护桩设计和施工提供依据。
By comparison with the data obtained from the field test pit excavation- the effect is satisfactory.
