Then the pile-soil stress characteristics and stabilizing mechanism of the composite foundation are fully discussed. Based on the close analysis of the influence factors of the vertical bearing capacity, circular aperture extension theory is employed to establish the computing formulas for the pile vertical stress and the foundation vertical bearing capacity, respectively. Moreover, with analyzing the features of the calculation parameters such as materials of gunite mortar, jet pressure, diameter of the jet pipe, pile length, pile layout, a design theory for chemical churning pile composite foundation is proposed. Then, the variation of the pipe deformation with loads, the deformation coordination of pile and soil are studied. And methods to decide pile-soil stress ratio and the compressive modulus are developed. Meanwhile, the corresponding design method and the design parameters are proposed. In addition, studies for construction technique and quality detection of the chemical churning pile composite foundation are presented.

研究结果显示，企业公关部门与企业基金会所能达成的企业目的相同，却是透过不同的方向去进行：企业公关部门偏向营利观点，而企业基金会则扮演非营利形象的角色，透过赞助艺文的方式，与公共关系部门形成相辅相承的的互补关系；在企业基金会的艺文赞助行为上乃是融合行销与公关的概念，形成企业「行销公关」的一环；另外在艺文团体与企业基金会的关系上，是走向双向「互助合作」，而非单向的「赞助」关系；最后，企业经营者应衡量企业的能力，从人员专业程度、企业资源及调整企业内外群众关系的能力来决定是否应设立企业基金会从事艺文赞助行为。
