（廣東省水利水電科學(xué)研究所 廣州 510 610）[提要] 對深基坑開挖中的預(yù)應(yīng)力錨桿或預(yù)應(yīng)力支撐的支護(hù)結(jié)構(gòu)的受力計算提出了相應(yīng)的計算方法，并通過工程實例的計算分析，說明預(yù)應(yīng)力在減少支護(hù)結(jié)構(gòu)的位移、改善受力狀態(tài)中的作用。

The analysis example of project illustrate that the prestress can decrease the displacement and improve the state of"mechanical in supporting structures.
Keywords: deep foundation pit; excavation; supporting structure; prestress; anchor rod; brace
