soil deposit meaning in Chinese
土壤沉积
Examples
- Mulch keeps the fruit cleaner and reduces the time and effort that goes into preparing the product for shipment and sale because rain splashed soil deposits are virtually eliminated
塑料薄膜覆盖使果实干净并减少运输和销售过程中清洗水果而花费的时间和精力，因为塑料薄膜覆盖完全防止了降雨把泥土溅到果实上。 - Setenaly according to the analyses from selected profiles , we know that , it is cold and dry in this region during the early holocene when east asian winter monsoon ' s influence is obvious , so , it is a transition period from sand deposit to sandy soil deposit , when the layers become thinner gradually from north to south . during middle holocene , it is warm and humid , influenced evidently by east asian summer monsoon , so , it is an obivious pedogenesis , when there are generally well - developped holecene palaeosol ( so ) from north to south , and the pedogenesis in the south is better than that in the north , the soil is also thicker than that of the north . from late holocene to now , the climate changes to be dry and cold , but its changing scope is smaller than that of last glacial period
2 、就所选剖面分析来看，本区在全新世早期气候回返，相对较寒冷干燥，东亚冬季风影响较明显，此时为沙层堆积向砂质土壤过渡，自北至南堆积的沙粒渐细；全新世中期气候温暖湿润，东亚夏季风影响显著，此时为明显的成壤期，表现在自北至南普遍可见发育较好的黑垆土层，且南部的成壤作用比北部好，土壤的厚度也要大；全新世晚期至今，气候向干冷方向转化，但变化幅度远小于末次冰期。 - Considering the similitude law for shaking table test , we study the test results and obtain some conclusions which are a ) generally , the silty soil in test box liquefies and the liquefied time has relation with the amplitude of acceleration , b ) when the intensity is on and above eight degree , the silty soil deposit will be liquefied dramatically , c ) the relationship of the pore water pressure is relevant to the cycle loading which represents when the cycle loading ranges from little to great , the relationship is represent as a concave curve , or else as a protruding curve and tends to stability . ( 3 ) based on the triaxial compression test and the resonant column test , some studies are made such as a ) the duncan - chang parameters of constitutive model , b ) the dynamic shear modulus ratio and c ) the damping ratio of the site soil deposits . in order to deal with the test data , a computer program is compiled
( 2 )利用小型振动台进行了k _ 0固结状态下粉土的振动液化模拟研究，通过分析正弦荷载作用下的试验资料，验证了粉土的孔隙水压力增长模式的合理性；从微分方程推导了基于土体振动台模型试验的相似律，并从模型实体、孔压时程曲线和相似律等方面做出了分析，得出了如下结论：在小型振动台试验中，模型箱中的粉土都发生了液化，液化的时刻和输入加速度幅值有关，而对频率的变化不太敏感；粉土在相当于8 9度地震烈度的加速度幅值作用下可能产生严重的液化；孔压的增长曲线形状与施加的荷载有关：当施加荷载为由小到大的形式时，曲线形状为上凹的曲线；当施加荷载为等幅的正弦荷载或荷载幅值由大到小时，曲线形状为上凸的曲线，且逐渐趋于稳定。 - Catastrophic damages to structure can be made by lateral permanent displacement , namely large ground displacement , on gently sloping ground induced by liquefaction of saturated soil deposits during earthquake , which is the main type of seismic damages of highways , railways , bridges , docks , embankments , buildings , underground structures and lifeline engineering in liquefied area . in recent ten years , studies on the new type of failure made by liquefaction have been carried out
地震过程中由于饱和砂土液化诱发的小坡度地面侧向永久位移即地面大位移对结构的破坏，是液化区公路、铁路、桥梁、码头、堤坝、房屋、地下结构与生命线工程震害的主要形式之一，近十几年来，人们越来越重视对这种新的液化破坏形式的研究。
