摘要:塑料排水板作为一种软土地基加固处理方法非常地有效,该方法通过排水固结的方式有效缩短固结沉降时间,并具有成本低、施工方便快捷的特点。同时,随着计算机技术的高速发展使得大量施工监测管理工程更加精确有效,因而结合两者的优势将使得软基处理工作更为高效。本文回顾了塑排板法以及固结理论的研究现状,了解塑排板法处理软土地基和固结沉降的相关状况。之后对运用塑料排水板法进行软土地基固结沉降相关的计算进行分析理解,明确固结沉降计算中所要涉及的相关参数。最后通过结合杭浦高速的工程背景以及相关数据,运用程序编制荷载—时间—沉降(PTS)曲线生成系统,系统通过对沉降相关数据的读取以及数据的参数化来做到PTS曲线的生成。74079

Soft foundation treatment of Hang Pu Expressway and The design of PTS curve system—plastic drainage board method
Abstract: As a kind of soft soil foundation treatment method, plastic drainage board method is very effective。 The method can effectively shorten the time of consolidation settlement through drainage consolidation, and has the advantages of low cost and convenient construction。 At the same time, with the rapid development of computer technology, a large number of construction monitoring and management projects are more accurate and effective。 Therefore, combining the advantages of both will make the soft foundation treatment work more efficient。 In this paper, the research status of plastic slab method and consolidation theory is reviewed, and the related condition of soft slab foundation and consolidation settlement is analyzed。 After that, the calculation of settlement of soft soil foundation is analyzed by using plastic drainage board method, and we can know the related parameters in the calculation of consolidation settlement。 Finally, combined with the engineering background and relevant data, and establish the load-time-settlement system by programming。 By reading the settlement data and the parameterization of data to generate the PTS curve。
KeyWords: soft soil foundation; plastic drainage board; consolidation settlement; PTS curve
