【摘要】：隨著國家“走出去”戰(zhàn)略的推進、“一路一帶”計劃的提出,越來越多中國基礎設施建設企業(yè)走向世界,參與國外基建設施的施工建設。本文依托中國路橋工程責任有限公司的“中、美、歐規(guī)范對比研究”課題,廣泛閱讀中國規(guī)范、歐盟規(guī)范、美國AASHTO規(guī)范,以樁基礎、擋土結構、地基處理為突破口,從巖土工程設計角度對比中、美、歐規(guī)范。本文通過中、美、歐規(guī)范文本的閱讀,對比中、美、歐巖土工程設計中的差異性,結合工程案例,對中、美、歐規(guī)范中樁基承載力計算、擋土結構的土壓力計算和穩(wěn)定性分析、砂石樁地基處理的設計計算的差異性進行分析。主要內容如下：1.簡明介紹了中、美、歐規(guī)范體系,指出中、美、歐規(guī)范的組成在應用范圍、規(guī)范獨立性、勘察規(guī)范集成度、是否注重資料引用等方面存在差異。中、美、歐規(guī)范的具體內容上存在廣泛的共同點,但在部分理論、計算模型、參數(shù)上存在差異性。2.對中、美、歐規(guī)范中樁基礎設計計算的差異性進行對比,重點對比了樁基豎向承載力計算的差異性,指出樁基豎向承載力的差異性主要由分項系數(shù)取用不同、常用勘察試驗參數(shù)不同、參數(shù)運用不同引起的。結合工程案例,定量分析了中、美、歐規(guī)范在樁基靜載荷試驗、靜力觸探試驗、旁壓試驗、巖石單軸壓縮試驗等勘察試驗方法確定樁基承載力的不同。3.針對擋土結構開展中、美、歐規(guī)范對比研究,對比中、美、歐規(guī)范在土壓力計算、抗滑移穩(wěn)定性驗算、抗傾覆穩(wěn)定性驗算、地基承載力驗算等方面的差異性。4.從強夯法、固結排水法、碎石樁法等地基處理技術開展中、美、歐規(guī)范的對比研究。結合工程案例,從設計計算的地基處治效果出發(fā),重點對比了碎石樁法在中、美、歐規(guī)范中的差異性。
[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.
