本文按弹性理论推导了计算矩形和条形基础外任意点沉降的公式,从而可以较方便地计算出基础间的相互影响,特别是计算条形基础房屋基础间的相互影晌。根据理论计算结果,本文第二部分分析了基础范围以外沉降随距离的变化性质;不同平面形状的条形基础房屋各点沉降的不均匀性以及条形基础房屋相互间的影响问题,同时从若干实例的突测沉降引证了理论分析结果。本文第三部分系根据理论计算结果对天然地基规范(НИТУ127—55)第51条控制相邻基础距离的公式的合理性和适用范围进行了分析和讨论。最后对相邻基础相互影晌的若干问题提出了初步意见。
In this paper, the formulae for calculating the settlement of any point outside the rectangle and strip foundation are deduced according to the elastic theory, so that the mutual influence between the foundations can be calculated more conveniently, especially the mutual influence between the foundations of the strip foundation. Based on the theoretical calculation results, the second part of this paper analyzes the nature of the change in settlement with distance beyond the basic range; the uneven settlement of each point of the strip-shaped basic house with different plane shapes and the mutual influence between the strip-shaped houses, and from several The sudden settling of the example cited the theoretical analysis results. In the third part of this paper, based on the theoretical calculation results, the rationality and application scope of the formula for controlling the adjacent base distance in Article 51 of the Natural Foundation Regulations (НИТУ127-55) are analyzed and discussed. Finally, preliminary opinions are given on several issues that affect the adjacent foundations.
