摘要
本文主要介绍了抗浮盲沟的概念、组成及其适用范围,并简要说明了抗浮盲沟各主要组成部分的作用。文中强调了抗浮盲沟的关键在于自溢排水,以实现建筑结构自重抗浮的目标。以深圳市某山地建筑为例,分析了抗浮设计中的重点难点问题。采用数值模拟的方法计算了抗浮盲沟的排水量以及坑底水头值,说明了将采用自溢排水技术的抗浮盲沟运用于山地建筑抗浮工程中是十分有效的,也为山地建筑抗浮工程提供了新的设计思路。
The concept,composition and application of anti-floating blind drainage ditch are mainly introduced in this paper. The role of each main component of anti-floating blind drain is also briefed. The key measure to accomplish the goal of anti-floating with the self weight is overflow discharge. A case study of the anti-floating for a mountain building in Shenzhen is carried out to analyze the difficulties in antifloating design. The discharge amount and the pressure at the building bottom are calculated by numerical simulation method. It is proved that blind drainage ditch with self overflow discharge technique is very effective for anti-floating in mountain building project,which provides a new idea for anti-floating design.
