“预应力锚索+桩板式挡土墙”支护结构应用研究

该文以下沉式通道的支护设计为例,提出了预应力锚索+桩板式挡土墙的防护方案,运用m法、水土合算法,以及瑞典条分法进行支护效果分析。结果表明,该方案既可以满足路堑边坡稳定性、安全性的要求,又可以减少施工开挖工作面,有效地减少既有建筑物的拆迁,在城市下沉式通道支护中具有良好的适用性和优越性。

Study on Application of Pre-stressed Anchor Cable + Sheet Pile Retaining Wall Supporting Structure

The article takes the supporting design of sunken passage as an example,puts forward the pre-stressed anchor cable + sheet pile retaining wall protective scheme,and analyzes the supporting effect by using the m method,economical method of water and soil,and Sweden slice method.The result shows that this scheme can not only satisfy the requirements of stability and security of road cutting side slope,but also decrease the construction excavating working face as so effectively to decrease the removal of the e...
