抗滑桩结构的力学分析和应用研究

MECHANICAL ANALYSIS AND APPLIED RESEARCH ON ANTI-SLIDE PILE STRUCTURE

抗滑桩是滑坡整治工程设计中的主要技术措施之一，本文通过对抗滑桩的力学性质和受力状态进行客观分析和评价，提出两种新型抗滑桩结构及其实践应用的可行性，即变截面抗滑桩和推力传递抗滑桩，特别是，推力传递抗滑桩技术，可以节省钢材８０％以上，从而大大地降低了抗滑工程造价，并且，从根本上改变了传统的抗滑桩的力学性质和桩身受力状态，值得深入研究、推广和应用。

Anti-slide pile is one of main technical methods in the designing of controlling project for landslides practice and experience in more than 30 years made clear that anti-slide pile had been applied and developed wildly. In the present paper. authors presented two new kinds of anti-slide Pile structures (altersection piles and transmitting piles) and their possibility of application by analysing and evaluating mechanical character of anti-slide pile,especially, transmitting Pile can save more than 80 percent of steel and change thoroughly the mechanical character of anti-slide pile as well as the stress state of pile body. So, this kind of pile is worth researching and appling improvely.
