一、前言: 无筋倒园台基础较普通钢筋混凝土柱基础能节约全部钢筋,还能节省混凝土20％左右。具有很大的经济价值(见文献[1]、[2]、[3]、[4]、 文献[4]曾对倒园台基础、变断面园平板基础以及正园台基础进行承载能力的对比试验,试验结果表明:倒园台基础与其他型式的基础相比,承载能力提高将近一倍左右。而沉降却较普通基础为小(见文献[3]).对于这些重要事实,用目前已经提出 I. Foreword: The foundation of the unreinforced inverted garden platform can save all steel bars compared with the ordinary reinforced concrete column foundation, and can save about 20% of the concrete. It is of great economic value (see literatures [1], [2], [3], [4], and [4]) that the bearing capacity of the foundation of inverted garden platform, slab foundation of variable section garden, and foundation of Zhengyuan platform In comparison tests, the test results show that compared with other types of foundations, the bearing capacity of the inverted garden platform is nearly doubled, while the settlement is smaller than the common foundation (see [3]).For these important facts, use the current Already proposed
