鸡西市77％的面积为沟谷连绵的山区,山地土壤中多为岗地白浆土,质地粘重,不易渗水,是冻胀性较强的土壤。这里属寒温带大陆性气候,冬季严寒漫长,多年平均气温为-3.6℃,一月份可达-30℃左右。该地区在上冻前,往往有1～2次降雨,谷坊蓄水后使坝体含水量提高。因此,鸡西地区建造的土谷坊坝在高含水量的情况下,受高寒的作用,冻胀破坏严重。为了 77% of the area in Jixi is covered with valleys and mountains. Most of the mountainous soil is white clay soil. The texture is heavy and not easy to seep so that it is a soil with strong frost heave. Here is a cold temperate continental climate, long winter cold, long-term average temperature of -3.6 ℃, up to -30 ℃ in January. In the region before the freeze, there are often 1 or 2 times the rainfall, Valley water storage to increase the water content of the dam. Therefore, the earth dam built in Jixi area in the case of high water content, by the role of alpine, severe damage to frost heave. in order to
