Concerning the research of the foundation some problems of a compound of half (1.The University of Zhejiang civil engineering department, Hangzhou in Zhejiang 310027;2.Too the principle work university civil engineering department, the mountain west is too original 030024 Summary:Aim at the rigid and compound foundation of half in the cement soil stake and CFG stakes of the extensive usage at the engineering practices to moderate some problems within researches, for example a stake that transforms the amount of mold, the cement soil stake and CFG stake soil should exertive coefficient β , the cement soil stake and the compound foundation quiet lotus of the CFG stakes of dints carry on trial method etc..Combine some concrete engineering, carried on to experiment the research and theories analysis to these problems;Put forward the cement soil stake transform amount of mold and a soil should the dint develop the coefficient of suggestion take the value and solve the mat layer constitution and the mat layers to compress the quantity to the correction method that the engineering practice the influence Keyword:Cement soil stake;Transform the amount of mold;CFG stake;A soil should dint exertive coefficient;The quiet lotus carries to experiment Medium diagram classification number:TU473.1 Cultural heritage marking code:A The cement soil stake and CFG stakes are a compound of extensive applied half foundations currently, among them, the cement deep agitation stake has already woven into the Peoples Republic of China profession standard 《 the building foundation processing technical specification 》 ( the JGJ79  91), the national standard of the CFG stake also in the establishment.The author met some problems in be engaged in the design of the cement soil stake, CFG stake, examine, study, among them, some problems really settle and transform the calculation to have the importance influence towards reuniting the foundation loading dint, but have no explicit p
