But bad construction control results in some low concretegrade of foundation piles and some broken piles.
在施工中,由于管理不善,造成部分基桩砼标号低于设计标号,并伴随有断桩等现象的工程质量事故。

Now the present code has got considerable changes in concretegrade of strength. In order to understand and put the present code into practice correctly, this paper has stated …
At the end of the paper, a stress strain response model of different concretegrade has been built only using the compressive strength, and this model coincides well with the experiment results.
