     Eddie McKay, a onceforgotten pilot is a subject of great interest to a group of history students in

Canada.

     It all started when Graham Broad, a professor at the University of Western Ontario, fofund McKay's

name in a footnote in a book about university history.McKay was included in a list of university alumni

(校友) who had served during the First World War, but his name was unfamiliar to Broad, a specialist

in military history.Out of curiosity, Broad spent hours at the local archives(档案馆)in a fruitless search

for information on McKay.Tired and discouraged, he finally gave up.On his way out, Broad's glance

happened to fall on an exhibiting case showing some old newspapers.His eye was drawn to an old

picture of a young man in a rugby uniform.As he read the words beside the picture, he experienced a

thrilling realization."After looking for him all day, there he was, staring up at me out of the exhibiting case,

"said Broad.Excited by the find'Broad asked his students to continue his search.They combed old

newspapers and other materials for clues.Gradually, a picture came into view.

     Captain Alfred Edwin McKay joined the British Royal Flying Corps in 1916.He downed ten enemy

planes, outlived his entire squadron(中队)as a WWI flyer, spent some time as a flying instructor in

England, and then returned to the front, where he was eventually shot down over Belgium and killed in

December 1917.But there's more to his story."For a brief time in 1916 he was probably the most

famous pilot in the world, "says Broad."He was credited with downing Oswald Boelcke, the most

famous German pilot at the time."Yet, in a letter home, McKay refused to take credit, saying that

Boelcke had actually crashed into another German plane.

     McKay's war records were destroyed during a World War ? air bombing on London-an explanation

for why he was all but forgotten.

     But now, thanks to the efforts of Broad and his students, a marker in McKay's memory was placed

on the university grounds in November 2007."I found my eyes filling with tears as I read the word '

deceased' (阵亡) next to his name, "said Corey Everrett, a student who found a picture of Mckay in

his uniform."This was such a simple example of the fact that he had been a student just like us, but instead of finishing his time at Western, he chose to fight and die for his country."

背景材料:
某山岭重丘区高速公路K29-000~K29+800路段进行路基施工,其中K29+000~K29+400为路堑开挖,原地面自然坡度65°~75°,地表1~3m为黏土,下为Ⅴ级岩石,不含水分,施工方拟采用药壶炮爆破法爆破,挖方共计13800m3,土方2000m3,石方11800m3;K29+400-K29+800为山坡路堤填筑,需要填方6000m3。原地面横坡为1:4.5,由于上段爆破石料较多,经强度检测,大于20MPa,施工方拟利用石方用水平分层填筑法填筑成土石路堤,土石比例1:2直接铺筑,松铺厚度50cm,接近设计标高时,改用土方填筑。
2.问题:
(1)路堤填筑的方法有哪些该工程采用的方法是否合理
(2)简要叙述路堤填筑的施工程序。
(3)该工程在土石路堤填筑施工时按含石量确定的松铺厚度是否合适应如何调整
