The results of this research show that gin grouting , compared with the traditional grouting technique , is a kind of grouting method which can save materials , simplify techniques , increase working efficient and make the foundation or curtain uniform , dense and durable . meanwhile , in gin grouting , it is more suitable to use computers to automatically monitor the grouting procedure , thus to reduce artificial influences and increase grouting quality 本试验研究成果表明gin法灌浆与传统灌浆工艺相比是一种节省材料、简化工艺，可提高工效并使基础或幕体均匀致密且耐久，同时更适用于计算机自动监控灌浆过程、减少人为因素影响，提高灌浆质量的灌浆方法。
Abstract : optimum design of individual foundation considering the effect of strength and deformation is discussed in this paper . the optimal mathematical model of determining the bottom surface demention of individual foundation under eccentric load is derived . the optimal solution is decided by method of optimization and the method we select is penalty fonction and complex method . the program of optimum algorithm is comiled and design and drawing of individual foundation is completed . the final results of engineering samples suggest that the cost of material and engineering amount can reduce approximatly 5 % - 6 % . a fair - sized economic efficiency can be received by using optimum method to design foundation 文摘:笔者讨论了独立基础在考虑强度和变形条件下的优化设计.导出了确定独立基础底面尺寸的优化数学模型，导出了偏心荷载作用下基础的高度和底面配筋的计算公式，求解优化解采用最优化方法的复合形法和罚函数法.通过基础实例和工程实例的计算表明优化设计可以节省材料和工程量5 16 .所以将本文优化方法用于基础设计，会产生较大的经济效益
