As for the parameters that relates to various phenomena in the inside and outside of the landfill, it is extremely abundant, and the interrelation is also complex. In addition, there are peculiar properties to the landfill site, and it influences. It is necessary to borrow the processing performance and the expression ability of the computer to appropriately control thelandfill that is such a complex system.Then, a current landfill researches are widely consolidated, and the program that calculate the stabilization process of waste in the landfill with the personal computer is completed.The set of equations with various phenomena in the landfill and the decision of necessary model parameters is obtained. The calculation program was able to be made though there were a lot of the parameters that had to be set, and the relations of each other were complex.1) The calculation program on one cell was made, and the influence of the parameter on the calculation result was examined.2) It succeeded in making the one dimensional calculation program that piled up the covering soil and/or the waste layer in one dimension and elucidating the biodegradation process of organic matter with the time variation of the quality of the leachate and the landfill gas.3) The influence of the parameters related to the infiltration of oxygen gas, the microorganism proliferation, and the amount of the neutralizing material was clarified, and the influence of the landfilling method was discussed by using the obtained program.4) Finally, a three-dimensional calculation method was shown.

至于与填埋场内外各种现象相关的参数，则是极其丰富的，相互关系也是复杂的。此外，垃圾填埋场还有一些特殊的性质，它影响着。填埋场是一个复杂的系统，有必要借助计算机的处理性能和表达能力，对填埋场进行合理的控制。并编制了在微机上计算填埋场垃圾稳定化过程的程序，建立了填埋场各种现象的方程组和必要的模型参数的确定，得到了虽然需要设定的参数很多，而且相互之间的关系也比较复杂，但还是能够编制出计算程序。1）编制了单电池的计算程序，2）成功地编制了覆盖土和覆盖层堆积的一维计算程序，并对计算结果进行了分析。3）阐明了氧气入渗、微生物增殖、中和剂用量等相关参数对有机物生物降解过程的影响，并利用编制的程序讨论了填埋方式对填埋场的影响。
