摘 要: | 论述框架结构房屋,当柱网密、柱距过小时,采用柱下联合桩基的必要性和适宜性,并用实例证明在某些情况下。联合桩基础将因群桩效应的引入使桩数减少而带来经济效益。同时指出对联合桩基础因承台底面弯矩减少等原因,不能简单套用单柱承台设计,以免造成浪费。

The design of combined pile-foundation under group column |
| |
Abstract: | The necessity and suitability of adopting combined pile-foundation under column in framed building with dense-column grid and close-column spacing are discussed in this paper. In some cases, the combined pile-foundation brings economic benefit by decreasing pile amount with action of pile group. Applying add-pole pile-cap design to combined pile-foundation is not economical because the bottom moment of its decreasing. |
