According to disadvantage of AS that the speed low of convergentiss and easily entering the stagnation,improving the AS in some aspect by the way that importing pheromone windows that the value of pheromone cannot exceed the window,only deposit the pheromone on the edge that belongs to the iteration shortest solution path,releasing additional pheromone to the edge belongs to the so-far shortest solution path,judging the situation of convergent and to reinitialize pheromone,optimizing the solutions by local search procedure at the end of every iteration,modifying the transition probability by add some problem specific parameters and so on.

本文主要运用蚁群优化算法(Ant Colony Optimization，ACO)来求解VRP。针对蚁群算法收敛性比较差，易于停滞的缺陷，通过使用信息素窗口限制、信息素的最大最小值，只更新信息素迭代中最好解，增加了精英的蚂蚁，信息素重新初始化之前先判断出汇聚情况，在每次迭代过程中加入局部的搜索进行优化，在对蚁群算法进行了优化时考虑选择概率当中加入与问题的相关参数等措施，从而使蚁群算法的收敛性得到大大提高，避免了算法的停滞现象。

The research work done is presented as follows:Compound dewatering technique of vacuum tube well is an effective technology for solving the dewatering problems of aquitard and interface relict water according to physical simulation test and field test. The variation laws, such as degree of vacuum, pore water pressure in different strata, have been studied. The results show that there is a certain scope of influence of vacuum in strata, and the vacuum degree in the horizontal direction decreases gradually with the increase of the distance from the main well; the change law of degree of vacuum in the vertical direction increases firstly and then decreases with the depth of soil strata, and changes with different soil nature and depth; changes of pore water pressure in soil strata has also shown a similar law of degree of vacuum.

The computational formula of dew point temperature was presented according to the physical feature of water vapor such as Michell's saturated water vapour pressure formula. Surface temperature inside wall body was also calculated. Then the comparison between them verified whether wall body has dew. At the same time, the temperatures of every material layer inside wall body were calculated. The partial pressures of saturated water vapour and actual partial pressures of water vapour for every material layer inside wall body were obtained. The two were compared so as to verify whether condensation appears inside wall body.
