heavy clay loam-
The bulk density was 1. 2 g cm - 1. the soil contents about 60 % of silts and about 15 % of clays. a slope adjustable flume of 3 by 8 m was subdivided into 15 mini - flumes of 0. 2 by 8 m
土壤顆粒以粉沙為主，粉沙粒占總量的60左右，粘粒約佔15左右，容重約為1 . 2gcm ~ （ - 1 ） ，試驗前將土樣風干並過1 1cm的粗篩。Based on the approximate estimation of wetted front edge of one dimension soil column, the design parameters of sdi were determined primarily
粘壤土濕潤鋒運移速度明顯慢于沙土，特別是容重較大時更為明顯。Design loads for buildings ; soil characteristics ; specific weight, angle of friction, cohesion, angle of wall friction
建築物的設計負荷.土壤特性值.比重磨擦角粘著力The addition of lime to saturated clay soils ( liming ) is a common agricultural practice, improving soil structure by encouraging crumb formation and making heavy soils more workable
加入石灰使其飽和是農業上常用的一種方法，通過促進小塊形成改變土壤結構，使粘重土壤變得可以使用。As for h2 and h3 derived from quaternary deposits, the textures of soils would become heavy because of soil erosion, whereas t2 and t3 of red soil of granite became sandification
土壤侵蝕會引起土壤機械組成的改變。對于第四紀粘土發育的紅壤，土壤質地粘重，而花崗巖紅壤，侵蝕使其趨向砂質化。The results are mainly as follows : sticky quality, tuber structure, the loose and tense degree, unit weight, ph value ( decreases in the few conditons that resulting acidity strengthening ), alkalinity increases in the same soil level, root quantity and macro - element content decreases ; there has a extraordinary difference between k, ca and mg, especially for pb and cd which shows that the collecting function of soil enhances under the disturbence conditon, and other micro - elements, such as zn > mn, cu, ni get decreasing. tourism activity is one of the key reasons for water body pollution. to different recreation types, the pollution degree has the obvious difference
各景觀區所取樣點中，土壤理化性旅遊破壞區所受影響最大，呈現出質地粘重、結構變差（以塊狀為主） 、同一層次土壤松緊度增大、根系變少、容重增大、土壤ph值增大（也有個別ph減少，以致酸性增強） 、堿性增強、大量元素降低，其中對k 、 ca 、 mg影響中有顯著性的差異（又以游道類影響最為顯著） 、重金屬元素（ pb和cd ）明顯增多、顯著性的差異最為明顯，其它微量元素（ zn 、 mn 、 cu 、 ni ）逐漸減少，表明旅遊活動干擾後土壤對pb和cd富集作用增強等特點。分享友人
