【摘要】 紧缺的土地资源、人口增长和产业聚集等问题引起了对土地需求量的增大,给我国很多城市带来了不同程度的人地矛盾。因此,造陆工程正引起越来越多的关注。目前我国造陆工程尚处于起步阶段,技术和管理水平有待提高。造陆工程特殊的施工环境和施工工艺对施工管理水平提出了较高的要求。因此,为保证工程的工期、质量和成本目标,需要发挥有效的施工管理。特别地,对施工工艺加以合理改进和创新,是施工管理过程中有效控制成本的方法之一,应加以推广。本论文阐述造陆工程中主要施工工艺和施工管理尤其是成本控制的要点。首先介绍了造陆工程在国内外的发展现状及前景,分析我国造陆工程发展应克服的障碍,即施工技术和管理水平的提高。然后对造陆工程主要施工工艺及管理和施工企业的成本控制相关理论进行介绍,并分析施工工艺对成本控制的影响。最后结合天津南港工业区造陆工程这一具体案例,对施工过程中一些重要的施工工艺及改进进行总结和经济分析,包括对隔埝工程、疏浚吹填工程和软基加固工程过程中一些重要的施工工艺的介绍;施工过程中,为保证质量、工期等要求对施工工艺的改进,如隔埝的加高、吹填方向的控制及软基处理前的浅层预处理和横向排水系统的改进,并对改进的效果和对成本控制的影响进行分析总结,识别成本控制要点,包括吹填标高的估计、对吹填土层的勘察和吹填方向的控制,吹填后形成的地形的把握等,进而得出节约成本的最优工程模式,以供此类工程参考和借鉴。本论文通过将施工管理及成本控制相关理论的介绍和天津南港工业区实际案例结合,对施工中相关施工工艺及改进加以分析,总结成本控制要点,对于提高造陆工程施工工艺技术,加强成本控制,提高企业施工管理水平,推广造陆工程中最优的工程模式,进而推动造陆工程在我国的发展,具有重要的理论意义和实践价值。更多还原

【Abstract】 With the land shortage of different degree of many cities in china caused by a lack of land resource and the increasing demand from population and industrial development, more and more attention is being paid on land reclamation project. Land reclamation in China, however, still develops at the early phase, with the level of techology and management need improving. The special construction environment casts higher requirement for methods and skills used to complete the project. The improvement in the construction methods should not only meet the need of quality and time of the project, but also be cost-saving. The proper improvement and creativity on construction methods to save cost should be introduced to other similar projects.This paper mainly introduces some key points of construction methods and cost control for land reclamation project. Firstly we introduce the application and development of land reclamation in china and abroad as well, analyzing the difficulties includling the improvement construction methods and cost control of construction companies. Then theories about construction methods and cost control are introduced, based on which the influence of construction methods on cost control is demonstrated. Finally, we present the case of Tianjin nangang industrial district, concluing and conducting economic analysis for the main construction methods used in separated dam project, Dredging and filling projects and soft soil engineering. During the construction phase , part of construction methods have been improved in order to meet the requirement of quality and time, such as the increasing the height of separated dam, control of filling direction, pre-construction for shallow soil engineering, the improvement of horizontal drainage system and so on. We conclude and analyze those outcome and influence on cost control, identifying the key points for cost control, include evaluation of the filling height, the reconnaissance of soil composition , the control of filling direction and the filling terrain, so as to promote the best- construction-way that can be referred by similar projects.This paper combine theories of construction methods and cost control with the case of Tianjin nangang industrial district, analyzing its construction methods and some improvement as well, finally concluding the best-construction-way of the project, which provides great value both theory and practice for improving construction methods and cost control and promoting the development of land reclamation in china.更多还原
