中文摘要: 在对边坡治理工程中常用的桩、墙及其组合结构设计与作用分析的基础上,提出了用于壅水冲刷条件下大型崩塌堆积体治理的一种新型工程结构——桩顶墙防护结构。桩顶墙结构通过采用不同于传统刚性连接方式的一种弱势连接方式,从而改变了结构的受力模式。展示了该结构的设计理念和细部处理技巧,通过简单的计算对比说明弱势连接方式的优越性,并以工程设计为例说明了这种新型结构在强冲刷作用下大型崩塌体岸坡防治中的应用优势。
Abstract:Based on the structure design and applicability analysis of several common composite pile-wall structures in slope protection engineering,a novel structure pile-underpinning-wall structure suitable for large-scale collapse bank slope under backwater erosion was proposed.This structure changed the bearing mode by using a vulnerable connection which is different from the traditional rigid type.Through an explanation on design conception,detailed treatment and simplified calculation comparison, the application advantage of this structure was demonstrated. Finally,Laohuzui collapse bank slope was taken as an example to show the usage of pile-underpinning-wall structure in practical engineering. It was proved that pile-underpinning-wall structure is an effective measure in large-scale collapse bank slope protection.
