【摘要】：截至2013年底，福建省高速公路通车里程已突破4000公里，在建里程超过2000公里。在建高速公路点多、线长、面广，建设管理任务相当繁重，用于高速公路项目的资金也在逐年递增。如何科学进行限额设计、合理控制高速公路项目造价，对福建省公路工程造价管理工作来说至关重要。对福建省高速公路路基工程造价进行合理、有效控制，其关键是确定不同地形条件与不同设计技术指标下，对路基工程建安费影响较大的各典型分项工程的工程数量。本文通过查阅相关公路、测量、测绘规范及专家的地形划分研究理论与研究结果，确定了地形划分的合理样本段长度，提出了适合福建省实际情况的地形划分方法；通过应用MATLAB软件确定了不同地形、不同车道数、不同设计速度条件下，各项技术指标实际服从的分布类型、分布的概率密度函数并拟定了各技术指标的合理取值范围；结合相关性分析结果，运用MATLAB及SPSS软件进行回归分析，确立了各“主要技术指标”与各路基典型工程数量之间的多元非线性模型。本文提出了适合福建省实际情况的地形划分方法，为设计人员进行工程地形划分、选定线形线位、拟定技术指标等工作提供了一定的参考；拟定了“不同地形、不同车道数、不同设计速度”条件下各技术指标的合理取值范围，为设计部门进行方案比选、管理部门进行项目审查提供了一定依据；建立了“主要技术指标”与工程数量之间的多元非线性模型，为设计部门进行方案比选及优化设计提供理论支撑，，为造价部门进行成本管理与控制提供基础依据，为管理部门的项目审查提供重要参考。
[Abstract]:As of the end of 2013, Fujian highway mileage has exceeded 4000 km, in the construction of more than 2000 kilometers of mileage in highway construction points, long, wide, construction and management of arduous tasks and funding for highway projects is also increasing year by year. How to limit the amount of scientific design, reasonable control of highway project cost management is of vital importance to highway engineering cost in Fujian province.
Effective control of reasonable highway subgrade engineering cost in Fujian Province, the key is to determine the different terrain conditions and different design specifications, the fee larger number of each typical project engineering of subgrade engineering construction. In this paper, by reviewing the relevant highway measurement, mapping specification and expert terrain division research theory and research results sure, a reasonable division of the length of the sample topography, proposes a terrain division method suitable for the actual situation of Fujian province; the different terrain was determined by using MATLAB software, different number of lanes, different design speeds, the distribution type of the technical indicators of actual compliance, the probability density function of the distribution and to develop a reasonable range of each technical indicators; combined with the results of correlation analysis, regression analysis was carried out using MATLAB and SPSS software, established the "major technical indicators" and the The multiple nonlinear model of the typical project number of subgrade.
This paper proposes a terrain classification method suitable for the actual situation of Fujian Province, for designers in engineering division of terrain, selected alignment, provide some reference to technical indicators; made the different terrain, different number of lanes, the reasonable range of different design speed under the condition of various technical indicators, according to the plan selected as the design department, management department of the project review provides a basis for the establishment of a "multi; nonlinear model between the number of the main technical indexes and engineering scheme, to provide theoretical support for selection and optimization design for the design department, provide the basis for the cost of the department cost management and control, provide important reference for project management review department.
