The central core of an earth dam is being placed by flood deposit red clay of weathered limestone. The original design specifies that the core material should be placed at a moisture content of 21-24%, to a dry density of 1.55g/cm~3 with 90% of good qualification, by employing 15-ton sheepsfoot rollers with 24 roller passes in 8—10 cm compacted layers. The natural water content of soils in the borrow areas is about 30%, and the borrow materials are excavated horizontally in layers by agricultural plowing method. The wet soils are dried by plowing and aerating and then hauled to the dam. In 1964, prior to the flood season, the rate of construction was rather slow, and dry loose layer, smooth surface, shear failure and poor bond between layers were often found, and there also occurred the splitting of soil layers after wetting by rain. As a result, the quality and speed of construction were greatly affected In order to cope with these problems, laboratory and field compaction tests have been carried out which show that by reducing the placement dry density to 1.50 or 1.51 g/cm~3, and increasing the moisture content to 24—28%, the requirement of stability and seepage can still be satisfied, but with a remarkable improvement of the plasticity and uniformity of the darn core, thereby those defects in quality control during construction can be basically prevented. Through the field compaction tests corresponding method of construction and compaction parameters are determined, and then actually applied in construction. The field compaction tests have also shown that the rubber-tired roller is superior to sheepsfoot roller, because the former permits higher construction moisture content, and excavation on vertical surface in the borrow area is also possible. The intervention between hauling the soil by trucks onto the dam and compacting the soil by sheepsfoot rollers is avoided. It has the advantage of simultaneously raising the dam core and the outer shells. A better uniformity of compaction is obtained and the bond between layers is also good enough though not so excellent as that produced by sheepsfoot-roller.

我国南方一座较高土坝的心墙采用了石灰岩风化洪积红粘土填筑,原设计填筑标准为干容重1.55克/厘米~3,合格率90%,含水量21~24%,用15吨羊足碾,压24遍,每层压实土厚度8~10厘米.料場天然含水量30%左右,用农业机耕方法逐层水平开采,翻晒碎土后上坝.1964年汛前施工中发现生产效率低,经常发生干松土层、光面、剪力破坏、结合不良等质量事故,还有雨后浸水分层现象,经常返工,对施工进度与质量都有很大影响.为了解决这些问题,曾进行了试验室及现場碾压试验,证明将填筑干容重降低互1.50或1.51克/厘米~3,含水量提高到24~28%,仍能满足稳定及防渗要求,而填土塑性、均勻性及耐水性有显著改善,基本上可解决施工中发生的一些质量事故,并通过现場碾压试验确定了相应的施工方法及压实参数,在工程上已实际采用.现場碾压实验中也表明气胎碾比羊足碾压实有显著的优点,可进一步提高施工含水量,有可能在料場使用立采工艺,解决汽车运土上坝与羊足碾碾压之间的矛盾,工效高,有利于坝壳与心墙平起,压实质量较均匀等,结合面质量也能满足要求,建议推广使用.

The excised stem tips of Mentha haplocalyx Briq. L. had been cultured in vitro. Seven days after culturing, various aqueous concentrations of MH were added to make 0.1 p.p.m., 1 p.p.m., 10 p.p.m., and 100 p.p.m. in the culture solution, as soon as some of the adventitious roots had been established at the base. In low concentrations of MH (0.1 p.p.m. and 1 p.p.m.), the explanted stem tips normally developed and, instead, the growth was slightly promoted. But under the higher concentrations of MH (esp. in 100 p.p.m.), the activities of apical meristem, after two weeks of treatment, had been greatly reduced or eompletely inhibited and no fnrther extention in length could be discerned. The distal ends of already grown adventitious roots showed elliptical swellings and simultaneously the roots ceased to elongate. Longitudinal sections of the tumefacient part exhibited remarkable incre- ment in size of the cortical cells which were separated from the stele. Descriptions of the morphological and anatomical changes of the young leaves treated with the higher concentrations of MH were also presented.

本文讨论了薄荷(Mentha haplocalyx Briq.)的离体茎端,在不同浓度的MH溶液作用下所产生的各种影响。薄荷的离体茎端,培养于怀特(White)基本培养液中,经过一星期待开始形成不定根时,分别加入0.1p.p.m.、1p.p.m.、10p.p.m.、100p.p.m.的MH溶液。在0.1p.p.m.、1p.p.m.浓度下,离体茎端的生长仍比较正常,并有一些促进生长的作用。除1p.p.m.浓度对叶肉细胞稍有扩大以外,对于茎端和叶子的大体结构,并未引起明显的变化。在10p.p.m.、100p.p.m.的浓度中,离体茎端的伸长受到抑制。尤其是在100p.p.m.的浓度作用下, 茎端的细胞一般肿大,细胞内高度液泡化,核仁变为分散的小颗粒。生长锥的细胞分层现象消失,周围的叶原基也显著膨大。根的生长与新根的形成也受到严重抑制,根端出现纺锤形肿大或具凹凸不平的皱褶。皮层及表皮层的细胞特别增大,引起了皮层与中柱的组织分离。在这些处理中,根端所受的影响最为强烈。
