桩基扶壁式挡土墙的设计及应用

Design and Application of Pile Foundation Counterfort Wall

在地形起伏较大之处所建的综合管廊常位于高填方路基内,此时需建设挡土墙以确保道路边坡及管廊的安全,且为了保证管廊结构安全,一般对管廊外挡土墙的设计要求也较高。为了说明此类挡土墙的设计过程,特以云南省保山市青堡路地下综合管廊外的桩基高扶壁式挡土墙为例,对其设计方法进行了简要分析。

The utility tunnel built in the place with large hypsographical undulation is often located in the high fill subgrade. At this time, the retaining walls are often required to ensure the safety of road slopes and utility tunnel. In order to ensure the safety of the utility tunnel, the requirements for the design of retaining wall outside the utility tunnel are generally higher. To illustrate the design process of such retaining walls, taking a pile foundation counterfort wall outside the underground utility tunnel in Qingbao Road of Bashan City in Yunnan Province as an example, its design method is briefly analyzed.
