桩侧阻 meaning in English

skin friction=shaft resistance
skin(side) friction=shaft resistance

The bottom resistance and the shaft resistance exert asynchronously , so it is necessary to adopt different coefficient . the thesis also points that it is important to adopt pile end ( side ) grouting and tapered piles
超长桩侧阻和端阻的发挥是异步的，即使是同一土层，其埋深不同发挥程度也是不同的，在承载力的确定中对每一层土应采用不同的分项系数。
In this paper , based on the static - load tests of tension piles in soft ground lying on the province of zhejiang such as zhongshan garden , gongchen bridge canal piazza , etc , the calculations of ascending displacement , developing mechanism of the side friction and utmost bearing capacity of the tension piles are studied
本文以中山花园、拱宸桥运河广场等浙江软土地区抗拔桩静载试验为背景，对抗拔桩抗拔承载力计算、上拔量计算、抗拔桩侧阻发展机理进行了分析研究。
