由中国深基础工程协会主办的大直径桩墩基础设计计算学术讨论会于1990年3月22日至24日在北京举行。出席会议的有来自15个省、市、自治区35个单位的51位代表。提交这次会议的论文有29篇,其内容主要包括大直径桩墩基础承载力和变形的设计计算方法、垂直和水平荷载的机理分析,以及工程应用经验诸方面。它们反映了自1987年3月中 The Symposium on the Design and Calculation of Large-diameter Pile Foundations sponsored by China Association of Deep Foundation Engineering was held in Beijing from March 22nd to 24th, 1990. Attending the meeting were 51 representatives from 35 units in 15 provinces, municipalities and autonomous regions. There are 29 papers submitted to the conference. The contents mainly include the calculation methods for the bearing capacity and deformation of the large-diameter pier foundation, the mechanism analysis of the vertical and horizontal loads, and the engineering application experience. They reflect the middle of March 1987
