【正文】 the China Academy of Building Research Establishment of the construction engineering technical code for JGJ1062003 J2562003 has been implemented for 10 years, the implementation of the effect is very obvious. High strain in pile on energy, stress and strain levels close to or reach the engineering pile, strain level, dynamic load of pile soil resistance to overe the penetration between pile and soil, to produce plastic deformation, resistance of pile 39。然而，經(jīng)過30多年的工程實(shí)踐，高應(yīng)變動(dòng)力試驗(yàn)檢測也有它的不足之處，檢測風(fēng)險(xiǎn)隨之而來，也曾遭到工程界的質(zhì)疑。高應(yīng)變法作用在樁上能量大,應(yīng)力和應(yīng)變水平接近或達(dá)到工程樁的應(yīng)力,應(yīng)變水平、動(dòng)荷載使樁克服土阻力產(chǎn)生貫入度,從而樁土之間產(chǎn)生塑性位移,樁對外的抗力主要通過位移產(chǎn)生,有了位移,樁側(cè)和樁尖土的阻力得到一定程度指揮。東北大學(xué)繼續(xù)教育學(xué)院畢業(yè)設(shè)計(jì)（論文）摘 要高應(yīng)變試樁法檢測基樁的承載力,已經(jīng)在國際上得到了樁基檢測界的一致認(rèn)可。我國在二十幾年的實(shí)踐基礎(chǔ)上,由中國建筑科學(xué)研究院編制了《建筑基樁檢測技術(shù)規(guī)范》JGJ1062003 J2562003至今已實(shí)施10年了,實(shí)施效果非常明顯。在樁頂測到的樁土響應(yīng)信號包含有承載力因素,所以基樁高應(yīng)變動(dòng)力檢測規(guī)范適用于判定基樁的極限承載力和樁身結(jié)構(gòu)完整性。為統(tǒng)一高應(yīng)變檢測方法,確保樁基工程檢測的質(zhì)量, 本文主要以高應(yīng)變動(dòng)力檢測作為研究課題，在闡述其原理和檢測過程的同時(shí)，淺析檢測時(shí)應(yīng)注意的問題，針對工程中遇到的問題探討高應(yīng)變檢測的風(fēng)險(xiǎn)性，并提出避免風(fēng)險(xiǎn)的方案。s mainly through the displacement, the displacement, pile and pile tip resistance of soil to some extent mand. In the pile soil pile top to the measured response signals including bearing capacity factors, so the pile high strain dynamic pile testing specification for applied to determine the ultimate bearing capacity and pile structure integrity. However, after 30 years
