2總體概述

2.1工程概況

XX地下人行過街通道位于南京市建鄴區(qū)江東中路，為連接江東中路東西兩側(cè)的地

下過街通道，由于所處位置地面交通不能中斷，因此采用矩形頂管法施工，選用兩條頂

管并行的方案，總寬度約12m,頂管段總長(zhǎng)91*2=182m,兩端設(shè)工作井，其中始發(fā)井位

于江東中路西側(cè)，始發(fā)井（不含樓梯段及附屬用房）長(zhǎng)29.3m,寬12m,深度約13.5m,

接收井位于江東中路東側(cè)，與侵華日軍南京大屠殺遇難同胞紀(jì)念館三期同建，接收井（含

出入口及樓梯段）長(zhǎng)58.04m,寬13m,深度約11.85m0地下過街通道下部有規(guī)劃南

京地鐵九號(hào)線，且距離較近。始發(fā)井南側(cè)設(shè)置過街通道附屬用房及出入口樓梯，北側(cè)設(shè)
