【摘要】：随着国家“走出去”战略的推进、“一路一带”计划的提出,越来越多中国基础设施建设企业走向世界,参与国外基建设施的施工建设。本文依托中国路桥工程责任有限公司的“中、美、欧规范对比研究”课题,广泛阅读中国规范、欧盟规范、美国AASHTO规范,以桩基础、挡土结构、地基处理为突破口,从岩土工程设计角度对比中、美、欧规范。本文通过中、美、欧规范文本的阅读,对比中、美、欧岩土工程设计中的差异性,结合工程案例,对中、美、欧规范中桩基承载力计算、挡土结构的土压力计算和稳定性分析、砂石桩地基处理的设计计算的差异性进行分析。主要内容如下：1.简明介绍了中、美、欧规范体系,指出中、美、欧规范的组成在应用范围、规范独立性、勘察规范集成度、是否注重资料引用等方面存在差异。中、美、欧规范的具体内容上存在广泛的共同点,但在部分理论、计算模型、参数上存在差异性。2.对中、美、欧规范中桩基础设计计算的差异性进行对比,重点对比了桩基竖向承载力计算的差异性,指出桩基竖向承载力的差异性主要由分项系数取用不同、常用勘察试验参数不同、参数运用不同引起的。结合工程案例,定量分析了中、美、欧规范在桩基静载荷试验、静力触探试验、旁压试验、岩石单轴压缩试验等勘察试验方法确定桩基承载力的不同。3.针对挡土结构开展中、美、欧规范对比研究,对比中、美、欧规范在土压力计算、抗滑移稳定性验算、抗倾覆稳定性验算、地基承载力验算等方面的差异性。4.从强夯法、固结排水法、碎石桩法等地基处理技术开展中、美、欧规范的对比研究。结合工程案例,从设计计算的地基处治效果出发,重点对比了碎石桩法在中、美、欧规范中的差异性。
[Abstract]:With the promotion of the country's "going out" strategy and the proposal of the "one Road" plan, more and more Chinese infrastructure construction enterprises are heading for the world. To participate in the construction of foreign infrastructure facilities. This paper based on the China Road and Bridge Engineering liability Co., Ltd. "China, the United States, Europe norms comparative study", widely read the Chinese code, the European Union Code. American AASHTO code, with pile foundation, retaining structure, foundation treatment as the breakthrough point, from the geotechnical engineering design point of view, the United States, Europe code. The differences in geotechnical engineering design in USA and Europe, combined with engineering cases, the calculation of bearing capacity of pile foundation, the calculation of earth pressure of retaining structure and the analysis of stability of soil retaining structure in Chinese, American and European codes. The differences of design and calculation of sand pile foundation treatment are analyzed. The main contents are as follows: 1. The specification system of China, America and Europe is introduced briefly, and it is pointed out that the composition of Chinese, American and European codes is in the scope of application and the independence of the code. There are some differences between China, America and Europe in terms of the integration of survey specifications and whether or not to pay attention to data citation. However, there are some common points in the specific contents of Chinese, American and European codes, but in some theories and computational models. The differences of design and calculation of pile foundation in the code of China, America and Europe are compared, and the difference of vertical bearing capacity of pile foundation is compared. It is pointed out that the difference of vertical bearing capacity of pile foundation is mainly caused by different subdivision coefficients, different parameters of commonly used survey tests and different application of parameters. Combined with engineering cases, this paper makes quantitative analysis of China and America. European code in pile foundation static load test, static penetration test, pressure test, rock uniaxial compression test and other survey test methods to determine the bearing capacity of pile foundation. Comparative study of European code, the difference between American and European codes in earth pressure calculation, anti-slip stability checking, anti-overturning stability checking, foundation bearing capacity checking and so on. 4. From the dynamic compaction method, consolidation drainage method. Comparative study on foundation treatment technology such as gravel pile method in China, USA and Europe. Combined with engineering cases, the paper focuses on the comparison of gravel pile method between China and the United States from the design and calculation of foundation treatment effect. Differences in European norms.
