83SONG OF YELLOW RIVER 2021/ 22复调音乐风格的多元化——对巴托克多调式半音体系对位结构的分析与研究周立冉摘 要:20世纪以来,复调音乐在历史发展的沉淀中经过许多作曲家运用现代风格与民族特色相结合的手法,在传统自然音调式的基础上把不同的音阶素材加以创新和丰富,并且继续保留自然音调式的风格与特性。
在世界经济文化发展与融合的前提下复调音乐创作呈现多民族、多层面、个性化与多元化的姿态。
而作曲家巴托克的作品中,用这种纵横相融合不同音列调式的半音体系手法诠释了时代鲜明、色彩饱满的音乐元素。
这样有利于复调音乐和主调音乐两种多声部音乐的相互借鉴、互相影响、融合发展,为音乐创作提供理想化的技术条件。
本文通过多调式半音体系的对位结构的研究在一定程度上启发复调音乐创作的理性思维结合巴托克多部作品,将理论基础带入其中,从复调音乐这个角度出发,深入研究和分析巴托克音乐风格中的多元化。
关键词:复调音乐;多调式半音体系;多元化;音乐风格中图分类号:J614.2 文献标识码:A作者简介:周立冉(1997-),女,中央民族大学在读硕士研究生。
一、巴托克多调式半音体系在巴托克音乐的素材原则中,将民间音乐元素与现代音乐风格巧妙融合的写作手法,是二十世纪复调音乐的显著特性。
现代作曲技法中各种音乐风格的多元化也极大地拓宽了多调式半音体系的发展空间。
这一时期的音乐在无论在调式音阶、写作技法、还是理论原则,不仅适应多种音乐风格,同时也扩充和丰富了大小调体系在调式音阶中的音乐内容与和声表达。
在不同音列以纵横交错的方式所形成的多种调式音阶依然建立在自然音音阶的基础上,这些新生音阶赋予了和声与调式新的内涵。
而在这些新生合成音阶中产生的升降音不是变化音级而是自然调式音阶中的自然音级的组成部分,这种包括了所有半音音级的音阶被称为多调式半音体系。
从《小宇宙4》第114首乐曲中可以看出,巴托克以主题和转位为根基在传统基础的调式音阶上进行了尝试与突破。

路基换填8%灰土施工方案
一、工程概况
G310线秦州至甘谷至武山公路升级改造工程QWSG18合同段,湿陷性黄土段落原地面、低填浅挖及路床处理需换填8%灰土,换填深度为0.8m。
二、用料组成及压实标准
1、用料组成
灰土系用一定量的石灰与土拌合夯压而成,其强度随时间缓慢增长,具有一定的水稳定性和不渗水性(为原土的10~13倍),灰土重量比为8:100。
土料采用粘性细粒土,不得用表面耕植土,土料中硫酸盐含量应小于0.8%,有机质含量应小于10%,土块粒径不大于15mm。
石灰采用熟石灰粉,石灰等级不得小于Ⅲ级,要求同产地、同品种、同规格,每200T为一批,不足200T也按一批计。
选定好合格的土料与石灰后,做8%灰土击实试验,检验数量每5000m3检验一次(重型击实),以此进行施工质量控制。
尤其是含水量的控制是关键的一个环节,结合灰土击实试验报告的参数指标,含水量一般控制在20%~23%为宜,最大不超过24%。
施工前应根据工程特点、设计压实系数、土料种类、施工条件等,合理确定土料含水量控制范围、铺灰土的厚度和夯打碾压变数等参数。
2、压实标准
路基基底换填灰土,采用22T压路机碾压,虚铺厚度0.36m。
压实标准见下表:
路基基底8%灰土压实标准
3、挖除原地面软质土,按照现场放出的边线桩及下挖标高控制分段开挖,挖至设计换填标高后,用推土机将基底推平。
按照换填地基顶面的检验标准自检合格后,报监理工程师检查验收,验收合格后,开始进行8%灰土填筑施工。
换填基底顶面验收标准见下表。
三、施工准备
1、填筑前提前做好储料准备工作,保证储量满足换填要求。
2、检验、检测所需施工机械设备、机具、测量试验仪器的性能,确保施工时运行正常。
设备、仪器配备表
四、路拌法施工
8%灰土施工工艺流程图
1、下承层施工:
路堑施工完毕后,必须用22T的碾压机械进行3~4遍碾压检验,并使之达到规定的压实标准。
在碾压过程中,如发现土过干、表层松散,应适当洒水;如土过湿,发生“弹簧”现象,应采用挖开晾晒、换土等措施进行处理。
凡不符合设计要求的路段,必须
根据具体情况,采取措施,使之达到规范规定的标准。
2、施工放样:
在施工现场附近引临时水准点,每隔20m钉出中线和边线桩,并在桩上标注出虚铺厚度标高,挂钢丝绳作为基准线,控制填筑高程。
3、备料:
⑴、采集土前,应先将树木、草皮和杂土清除干净。
⑵、土中的超尺寸颗粒应予筛除。
⑶、应在预定的深度范围内采集土,不应分层采集,不应将不合格的土采集一起。
⑷、对于塑性指数大于12的粘性土,可视土质和机械性能确定土是否需要过筛。
⑸、施工前根据各段8%灰土的宽度、厚度及预定的干密度,计算各路段需要的干燥土的数量。
⑹、根据料场土的含水量和所用运料车辆的吨位,计算每车料的堆放距离。
⑺、在预定堆料的下承层上,在堆料前应先洒水,使其表面湿润,但不应过分潮湿而造成泥泞。
⑻、土装车时,应控制每车料的数量基本相等。
在同一料场供
料的路段内,由远到近将料按距离计算卸置于下承层表面的中间或上侧。
卸料距离应严格掌握,避免有的路段料不够或过多。
堆料每隔一定距离应留一缺口。
⑼、土在下承层上的堆置时间不应过长。
运送土只宜比摊铺土
工序提前1~2d。
4、摊铺土:
⑴、按照已钉出挂设的20m方格网线的虚铺厚度摊铺,摊铺
采用路拌法进行施工。
换填8%灰土施工时摊铺厚度30cm,按虚铺系数1.2考虑,灰土的生产含水量为20%~23%(占干土重),施工时根据灰土击实试验报告的参数再进行适当调整。
⑵、摊铺土应在摊铺前一天进行。
摊铺长度按日进度的需要量
控制,满足次日完成摊铺、碾压成型即可。
雨季施工,如第二天有雨,不宜提前摊铺土。
⑶、将土均匀地摊铺在预定的宽度上,表面应力求平整,并有
规定的路拱。
⑷、摊料过程中,应将土块、超尺寸颗粒及其他杂物拣除。
⑸、如土中有较多土块,应进行粉碎。
⑹、检验松铺土层的厚度,应符合预计要求。
⑺、除洒水车外,严禁其他车辆在土层上通行。
5、洒水闷料:
⑴、已平整的土含水量过小,应在土层上洒水闷料。
洒水应均
匀,防止出现局部水分过多的现象。
⑵、严禁洒水车在洒水段内停留和调头。
⑶、细粒土应经一夜闷料;中粒土和粗粒土,视其中细土含量
的多少,可缩短闷料时间。
6、摊铺石灰
⑴、土料闷好后,应用平地机整平,以便在土料上能够均匀地
摊铺石灰。
⑵、土层整平后,便可按试验厚度摊铺石灰。
7、土料和石灰的拌和
⑴、石灰摊铺完成后,便可进行土料和石灰的拌和,拌和采用路拌法,拌和机必须保持匀速前进,禁止忽快忽慢。
⑵、拌和机前进时,铧犁要完全插入土层底部,保证土料能够完全翻起,拌合机至少翻犁2~3遍,从而保证土料和石灰拌和均匀。
8、整形:
⑴、8%拌和均匀后,应立即用平地机初步整形。
在直线段,
平地机由两侧向路中心进行刮平;在平曲线段,平地机由内侧向外侧进行刮平。
必要时,再返回刮一遍。
⑵、对于局部低洼处,应用齿耙将其表层5cm以上耙松,并
用新拌的混合料进行找平。
⑶、如需再用平地机整形一次。
应将高处料直接刮出路外,不
应形成薄层贴补现象。
⑷、每次整形都应达到规定的坡度和路拱,并应特别注意接缝
必须顺适平整。
⑸、在整形过程中,严禁任何车辆通行,并保持无明显的粗细
集料离析现象。
9、碾压:
⑴、路基基底换填碾压时,灰土表面要潮湿,碾压遵循:先两
侧后中间,先静压后振动再静压的操作程序压实,压路机行驶速度控制在2km/h以内,碾压分初压、复压和终压。
⑵、初压(即静压)采用22t中型压路机,关闭振动装置,先
静压两遍,起整平和稳定混合料的作用。
⑶、复压时打开振动装置,弱振两遍,强振两遍,当压实密度
达到设计和规范要求时复压停止。
⑷、终压时压路机静压1~2遍。
⑸、碾压时,区段交接处应重叠压实,纵向搭接长度不得小于
3m,纵向行与行之间的轮迹重叠压实不小于0.3m。
10、接缝和调头处的处理:
⑴、同日施工的两工作段的衔接处,应采用搭接。
前一段拌和
整形后,留5~8cm不进行碾压,后一段施工时,前段留下未压部分,应再加部分灰土,并与后一段一起碾压。
11、养护
8%灰土压实后,应按规定进行养护。
五、技术要求及质量保证措施
1、技术要求
⑴、基底土质必须符合设计要求。
⑵、配料正确,拌合均匀,分层虚铺厚度符合规定,碾压夯实,
表面无松散、翘皮。
⑶、分层留接茬方法正确,接茬密实、平整。
2、质量保证措施
⑴、按设计标高尺寸挖除原地面软质土后,按照有关标准进行
自检,合格后报监理工程师检查验收,验收合格后,方可进行灰土填筑施工。
⑵、配料、拌合由试验员现场盯班,用专用量斗量灰、量土,
严格控制灰土的比例不超出验收标准。
拌合均匀,颜色一致。
⑶、由现场施工员、工点技术员共同检查接茬台阶留置情况,
并报监理工程师验收,合格后在进行填筑。
碾压成型后专门对接茬处进行密实度检测试验,合格后方可进行下道工序的施工。
六、检测验收
路基换填灰土,必须层层检测试验,并做记录,自检合格后报请监理工程师抽检验收,符合要求后方可进行上层的填筑施工。
检验频次:路基每100m检验两个断面,每个断面检验3个点(左、中、右),压实系数k30和孔隙率η检验,纵向每100m检验6点,其中左右距路肩边线1.0m处各2点,路基中部2点。
检验方法按《铁路工程土工试验规程》(TB10102)规定的试验方法检验,压实系数检验采用灌砂法。
七、施工注意事项
1、找平验收:灰土最上一层完成后,应拉线检查标高和平整度,超高处用铁锹铲平,低洼处应及时补打灰土。
2、雨天不准施工。
3、灰土地基完工后,应及时进行下道工序的施工,否则应临时遮盖防日晒雨淋。
4、分段铺设灰土时,要严格执行留置接茬的规定,接茬的茬子应垂直切齐,切成台阶形式,台阶高度不大于0.3m,宽度不大于1.0m。
5、当地下水位高于基坑时,施工前应采取排水或降低地下水位的措施,使地下水位经常保持在施工面以下0.5m左右,3d内不得受水浸泡。
