【摘要】：采用盾構(gòu)法進(jìn)行隧道施工,難免會引起地層移動而導(dǎo)致不同程度的沉降,而采用Peck公式進(jìn)行沉降預(yù)測時(shí),首先要利用實(shí)測數(shù)據(jù)對該公式進(jìn)行驗(yàn)證,并給出適合該地域的計(jì)算參數(shù)。文章利用合肥軌道交通盾構(gòu)施工中的地表監(jiān)測數(shù)據(jù)對Peck公式進(jìn)行驗(yàn)證,同時(shí)計(jì)算出沉降槽寬度參數(shù)和地層損失率,為該公式在合肥盾構(gòu)施工過程中預(yù)測地表沉降值提供了依據(jù)。
[Abstract]:Using shield method in tunnel construction will inevitably cause stratum movement and result in different degrees of settlement. When using Peck formula to predict the settlement, the formula should be verified by the measured data. The calculation parameters suitable for the region are also given. This paper verifies the Peck formula by using the surface monitoring data of Hefei rail transit shield construction, and calculates the parameters of settlement trough width and formation loss rate, which provides the basis for predicting the surface settlement value in the course of shield tunneling construction in Hefei.
