摘要

在北京市北三环路和平东桥－太阳宫西路段热力管线工程中，依据设计热力隧道要下穿一处面积为23.4 m× 24.5 m的地表一层砖砌群房。由于隧道埋藏浅，且所处于富水粉质粘土之中，其抗扰动能力很差，常规的施工降水对强化土体效果甚微，经评价认为，普通的施工方法必然会造成很大的地表沉降而危及地表房屋安全，同时，由于土体自稳能力极低，对施工亦存在很大的安全隐患。基于此，选定在不降水的条件下，采用水平长管棚支护技术和在隧道上半断面注浆技术，实现阻水、固土、均一沉降的目的，其有效地控制了土体沉降，保证了隧道安全贯通和地表建筑的安全使用。

Abstract

During construction of Hepingdong Bridge – Sun Palace thermal power pipeline in Northern third loop road of Beijing City

the pipeline tunnel would go through beneath a couple of single-floor houses

whose area is 23.4 m×24.5 m. Due to the shallow overburden and the saturated microfine sandy clay

which is plastic and soft plastic

the strata is very weak in resisting interruption. The traditional dewatering is limited to improve the nature of the strata. Based on calculation

it is believed that the common construction method would necessarily cause much settlement and endanger the houses. Meanwhile

as the strata are hard to stand up

safety problems may be triggered in construction. In view of these

the level long steel pipes are adopted to support soil mass and grouting in the upper half face of the tunnel is operated to prevent ground water and strengthen soil without dewatering. These two methods effectively control the settlement of ground surface and ensure the perforation of the tunnel in time and running of the houses in security.
