主要针对312国道镇江段香草河大桥和汤龙公路大桥采用先简支后结构连续部分预应力砼组合箱梁的施工中，在底板制作、钢筋绑扎、混凝土浇筑、预应力张拉、箱梁安装、组合体系转换等方面所采取的质量控制措施，本文分析对比了两座桥施工中好的做法及出现的质量缺陷，提出一些防治、处理措施及建议。

The mutagen mechanism is presumed single factor dominant.(4)There was 85 percent transvertion in mutagen spectra, and they were all G:C→T:A transvertion. The maximal possibility of mutagen mechanism is analyzed as followed:ion beam implant → breakage cell surface and enter the interior → stimulate plentiful radical born → radical oxidize and damnify DNA → G becomes 8—oxoG → 8—oxoG pairing A → result in G:C→T:A transvertion(5)Production of transition was presumed that ion beam implantion damnified DNA, stimulate activity of MMR interveniented by methyl reducing.
