The present study investigatated the effect on the diversification of weed community, including weed abundance, dominance, evenness, biomass, and mean height after mulching straw and intercropping white clover in the tea plantation from 2005 to 2006. The results were as follows: 16 families and 31 species were found in total. In April, the dominant species characterized with slow growth, lower biomass, and less than 30 cm height; in July those who grow faster with higher biomass and height became dominant; In September, these malignant communities reduced, while the oxalis and diffusa characterized with lower biomass and low height gradually increased. In the three seasons, the weed abundance, community diversity and evenness increased, and the dominance, the biomass and average height of weeds remarkably reduced after intercropping white clover and muching straw.

结果表明：茶园共有杂草16科31属31种，春季（4月）以生长速度较慢、生物量小、株高在30 cm以下的杂草为主，夏季（7月）以生长快、植株高和生物量大恶性杂草为主，秋季（9月）恶性杂草开始减少，酢浆草、白花蛇舌草等生物量小、株高矮的杂草逐渐增多；稻草覆盖处理茶园春、夏和秋季3个观测时期杂草物种丰富度、多样性、均匀度等指数均高于清耕对照，优势集中性指数低于清耕对照；间种白三叶草处理春、夏和秋季3个观测时期杂草总数量和生物量均显著低于清耕对照，夏、秋季杂草平均株高显著低于清耕对照；稻草覆盖和间种白三叶草处理春季茶芽重和产量显著高于清耕对照，鲜叶中游离氨基酸含量高于清耕对照，茶叶感官评审得分高于清耕对照处理。

Circular and catenary always represent the shapes of minor principal stress soil arch between two parallel walls, but which shape should be used in the calculation of active earth pressure on two parallel walls remains disputed. Considering fully developed wall friction or partially developed wall friction, circular and catenary, the two shapes of minor principal stress soil arch between two parallel walls are theoretically analyzed. According to the shapes of soil arch, the coefficients of earth pressure corresponding to different angle of internal friction and that of wall friction are obtained, and the formula of active earth pressure on two parallel walls is derived.

鉴于计算平行墙间侧土压力时关于土体小主应力拱形的选择尚存在争议，考虑墙土摩擦角充分发挥和部分发挥两种情况，对平行墙间土体小主应力圆弧拱和悬链线拱分别进行了分析，得到了对应于不同内摩擦角和墙土摩擦角的侧上压力系数，以及平行墙间侧上压力的理论公式。
