简介薛涛其人及其在成都的纪念地。
某施工单位承包了二级公路H合同段路基工程,其中K14+230~K16+380为填方路基,填料主要来自于邻近路段的路堑挖方碎石土,其石质成分是强~弱风化片岩、千枚岩和板岩,石料含量占总质量40%~70%。施工中发生如下事件: 事件一:施工前,在路基填料区获取相应的土样,根据公路土工试验过程中的标准方法来进行击实、塑限、液限试验,对土样的颗粒进行分析,取得土样的塑性指数、液塑限、最大粒径等相关的物料力学性质的数据。 事件二:在施工现场的填筑试验中,采用松铺厚度为30cm、40cm分别进行填筑,在每一种松铺厚度进行填筑的时候,在路基的表面设置多个固定的测点,在这些测点上进行高程测量和灌砂法的检测,对其沉降差进行计算,以此获取沉降差、压实度随着压实遍数的变化规律,最终得到松铺厚度以及碾压遍数等施工工艺的参数,其中压实的质量采用沉降差≤2mm和压实度来作为其标准。 事件三:填筑过程中,主要采用分层填筑,局部路段采用混合填筑。土石混填路基的边坡采用码砌施工工艺成型,采用先填筑后码砌的施工方式,即先在超过路基宽度要求的一定范围内将填料摊铺、压实,然后再按照路基宽度要求进行刷坡,最后将边坡码砌好。 K14+230~K16+380可否按土石路基进行填筑控制?说明理由。 通过事件一中的试验,还应得出哪些物料力学性质的数据? 事件二中还需要获取哪些施工参数? 指出事件三中路基填筑过程中的错误做法。

Good Table Manners Manners play an important part in making a favorable impression at the dinner table. Here are some general rules: Napkin (餐巾) use The meal begins when the host unfolds his or her napkin. This is your signal to do the same, so place your napkin on your lap. Unfold it completely if it is a small napkin. Or in half, lengthwise (纵向地) ,if it is a large dinner napkin. If you need to leave the table during the meal, place your napkin on your chair as a signal to your server that you will be returning. Once the meal is over, place your napkin neatly on the table to the right of your dinner plate. Do not refold it. Use a napkin only for your mouth. Never use it for your nose, face or forehead. Use of utensils (餐具) Start with the knife, fork or spoon furthest from your plate, and work your way in, using one utensil for each course. If soup is served, remember to spoon away from yourself. This helps stop the drips. Do not put the entire soup spoon in your mouth. Instead, fill a soup spoon about 75 per cent with soup, and sip(啜饮)it from the side noiselessly. After finishing dinner, place the knife and fork parallel to one another across the plate with the knife blade facing inward toward the plate. Using your fingers Here's a list of finger foods: sandwiches, cookies, small fruits or berries with stems, French fries and potato chips, and hamburgers. Chew(咀嚼)with your mouth closed and don't make noise; don't talk with your mouth full. Bread must be broken with your hands. It is never cut with a knife. Don't pick something Out of your teeth. Instead, excuse yourself to the bathroom. If possible, try not to cough at the table. Do not put your elbows (肘) on the table. In France, it is essential to have both hands above the table at the same time. Do not put bones or anything else on the table. Things that are not eaten should be put on your plate. The napkin is used only for().
