| 摘 要： | 结合湖南长沙潇湘大道上一路堤式加筋土挡墙,计算了不同筋材间距情况下相应的初始应变。同时计算了在相同条件下,未施加预应力与施加预应力墙面侧向位移的差异。研究表明:适当调整筋材间距和控制预张拉筋材初始应变是一种十分经济有效的方法。

| Abstract: | Based on the reinforced retaining wall for an embankment on Changsha Xiaoxiang Ave.,the relevant initial stress under different kinds of bar spacing is figured out.Meanwhile,under the same condition,the differences of wall lateral displacement between the two circumstances(being prestressed or not) are calculated.The results can show that it is a very economy and effective way to adjust reinforcement spacing appropriately and control the initial strain of the prestressed bars. |
