路基檢測摘要
Abstract: The roadbed is a linear structure, with long lines, and nature-Jiemian the characteristics of stability to a large extent by the local natural conditions by the decision. So in-depth investigation of the natural conditions along the road, to grasp the laws of nature and natural factors of stability of the roadbed, according to local conditions and the use of technical measures to achieve the right for roadbed construction and conservation purposes.
Factors affecting the stability of the roadbed including natural factors and human factors. The main factors are the natural topography, climate, hydrology and hydrogeology, geological conditions, such as plant cover. Human factors mainly referring to load, the roadbed structure, construction method, conservation measures. There is also along the nearby man-made facilities such as reservoirs, irrigation and drainage channels, paddy fields and human activities. Roadbed along the design should have humidity and humidity changes and take corresponding measures to regulate the water temperature to ensure sufficient stability of roadbed.
Key words: roadbed construction; roadbed stability control measures
❷ 一些路基路面試驗檢測技術的問題
摟主在考試驗員吧,問題太多,我就是專門從事公路工程施工的,所以對你問的這些問題,其實都不是什麼大問題。這些都是搞工程試驗檢測的人員應該掌握的基本常識。你可以慢慢的去翻書,慢慢的去體會,這樣比別人告訴你要理解透徹得多。建議你看如下的規范:《公路橋涵施工技術規范》,《公路路基施工技術規范》,《公路路面基層施工技術規范》,《公路土工試驗等規程》 以及上面你所提到的《公路工程質量檢驗評定標准》,另外說明一下,試驗是需要實際操作才能理解掌握的,憑空想像只能給你造成誤解。

樁基工程質量問題http://www.e-qdpm.com/news/showIt.aspx?treeid=3095&id=5589這篇雖然是科技論文,但是我覺得他翻譯成「pile foundation quality question」很不妥當,我將他修改成problems of pile foundation quality,,從漢語語法之角度考慮,這里的問題兩個字是多餘的,去掉更好,你自己看看吧!

Pile foundation is widely used as the main basic structure of high-rise buildings,super-large bridges,deep water wharf and Offshore oil platform. During recent years,there are many bases of pile foundation quality affecting the normal working and safety of the building structures. Pile construction has high impercephbility and whose quality presents many incertitude factors,from an angel of qualitative inspection of the foundation piles, it has important significance for ensuring the quality and safety of foundation pile projects to modify the inspection methods and improving the inspection quality and the reliability of inspection & assessment results,it is also one of the research hotspots in foundation pile field.
The main functions of low strain reflection wave method is to inspect the pile integrity, such as the judgment of pile defects positions, the checkout of pile lengths, and the qualitative estimation of the concrete strength grade,the judgment of the pile quality using the signal of reflected_wave curve accurately, the elimination of the project concealed harzard,and the estimation of foundation pile quality.
This paper studied on the low strain reflection wave method for measuring of pile integrity made of Kelvin nonlinear elastic materials, set up a new one-way fluctuant model to treat the problems of piles made of Kelvin nonlinear elastic materials, gave out a dynamics equation of control volume,and inced the relation between pile axial forces and axial strain using the constitutive relation of one-way nonlinear elastic materials, put forward a new calculation method for the fluctuation of one-way nonlinear elastic materials, simulated the pile-top speed response time history curve (or displacement, acceleration) numerically using program written in FORTRAN language, finally the author set up a curve database of the foundation piles existing integrity problem for the integrity inspection of foundation piles in the future.
