某沿海城市电力隧道内径为3.5m，全长乙9km，管顶覆土厚度大于5m，采用顶管法施工，合同工期1年，检查井兼作工作坑，采用现场制作沉井下沉的施工方案。
电力隧道沿着交通干道走向，距交通干道侧石边仅2m左右。离隧道轴线8m左右，有即将入地的高压线，该高压线离地高度最低为15m。单节硷管长2m，自重10t，采用20t龙门式起重机下管。隧道穿越一个废弃多年的污水井。
上级公司对工地的安全监督检查中，有以下记录：
(1)项目部对本工程作了安全风险源分析，认为主要风险为正、负高空作业，地面交通安全和隧道内施工用电，并依此制定了相应的控制措施。
(2)项目部编制了安全专项施工方案，分别为施工临时用电组织设计，沉井下沉施工方案。
(3)项目部制定了安全生产验收制度。

针对本工程，安全验收应包含哪些项目

In the second half of each year, many powerful storms are born in the tropical Atlantic and Caribbean seas. Of (91) , only about half a dozen (92) the p, circling winds of 75 miles per hour or more that give them hurricane status, and several usually (93) their way to the coast. There cause millions of dollars of (94) , and bring death to (95) numbers of people.
The great storms that hit the coast start (96) innocent circling disturbances hundreds, even thousands of miles out to sea. As they travel aimlessly over water (97) by the summer sun, they are carried westward by the (98) winds. When conditions are just (99) , warm, moist air flows in (100) the bottom of such a disturbance, moves upward through it and comes out at the top. In the (101) , the moisture in this warm air produces rain, and with it the heat is converted to energy in the form of p winds. As the heat increases, the (102) hurricane begins to swirl in a counter-clockwise motion.
The average life of a hurricane is only about nine days, but it contains almost (103) power than we can imagine. The energy in the heat released by a hurricane’s rainfall in a(n) (104) day would (105) the entire electrical needs of the United States for more than six months. Water, not wind, is the main (106) of death and destruction in a hurricane. A(n) (107) hurricane brings 6-to 12-inch downpours (108) in sudden floods. (109) is the powerful movement of the sea-the mountains of water moving toward the low-pressure hurricane center. The water level (110) as much as 15 feet above normal as it moves toward shore.
