There are many problems in the carling forming and unloading processes such as expand and shrink of U section wall, the torsion of U section and the warp of carling head. These problems are concerned by the carling factories and do not solved for a long time. The mechanism of the carling forming and spring back is analyzed. The carling forming and spring back processes are simulated by KMAS software. The warp of carling underside is researched by half analytic and half experiment method and the best scheme is found by this method.

The multiphase tectonic activities above clearly controlled the move and gather of salifying brine, the strongth of salt-forming and the deposition of salt-bearing strata. With the pass of time, the salt-bearing strata thickened gradually from northwest to east and southeast, and the distribution of the thickness trended towards complicated; the measurement of the halite deposition extended towards east too; in the early Palaeogene and the Neogene, strong multiphase tectonic activity was a disadvantage to salt-forming, but in the middle and late Palaeogene, weak multiphase tectonic activity, which resulted in slow and sustained subsidence of the basin, was greatly advantaged to it, especially to potash-forming.

古近纪和新近纪成盐卤水的迁移和聚集、成盐作用的强弱以及整个含盐系的沉积发育明显受到上述构造活动的控制：含盐系的厚度随时间由北西向东、向南逐渐增厚，且厚度分布逐渐趋于复杂化；石盐岩的沉积规模和范围也逐渐向东扩大；古近纪早期和新近纪强烈的构造活动对于成盐作用而言是一种干扰因素，而古近纪中、晚期相对较弱、导致盆地缓慢持续沉降的构造活动对成盐，尤其对成钾作用则极为有利。
