一、问题提出的经过1955年秋季,东北清河水库某粘土场开挖排水试槽时,地质部911队叶政祥同志发现土层中含有多量红褐色(锈色)与古生物学上的“海百合茎”相似的大小不一的土条土柱(经由0.8—1.5公分长3—5公分),干时非常坚硬,湿时可以揑破。定名为“岗土”。并于1957年2月在水文地质工程地质月刊发表文章予以论述。认为“岗土”不适宜于做筑坝材料。以后水利部张含英副部长及苏联专家康德拉什克同志、蔡那奇维奇同志曾先后提出应做夯实试验、注水试验及碾压试验,进一步证明,这种土能否压实,
First, the issue put forward After the autumn of 1955, a clay field excavation of the Qinghe Reservoir Northeast trial trench, the 911 team of Comrade Ye Zhengxiang geology department found that the soil contains large amounts of red brown (rust) and paleontology “sea lily stem ”Similar to the soil of different sizes soil column (through 0.8-1.5 cm long 3-5 cm), when dry is very hard, wet pinch broken. Named “post”. And in February 1957 in hydro geo-engineering geology Monthly published articles to be discussed. That “Kong Gang” is not suitable for dam materials. Later Vice Minister Zhang Youying of the Ministry of Water Resources and Comrade Ludwik Kantilaush, expert of the Soviet Union, and Cainchi Civic made suggestions that they should make compaction tests, water injection tests and rolling tests to further prove whether such earth can be compacted,
