The routes, roadbeds, bridges, tunnels, interchanges, facilities along the lines and other professional projects involved in highway design are closely related to highway land use.
Earth borrow should be combined with water conservancy construction, such as river improvement, lake cleanup and farmland irrigation facilities.
Earth borrow is better combined with the transformation of farmland, the construction of water conservancy, the excavation of fish breeding or lotus cultivation ponds and the development of aquaculture industry.

Introduction
The professional building structure identification organization usually utilizes correlation equations of PBD fire code to verify design safety for building structure, and fire damage examine tables or experimental investigation to determine building structure safety for building after a fire.
Concrete material is constituted with cement, sandy soil, aggregate and water to cement by hydrate.
The general strength concrete compressive strength lost 6 - 10 % in temperature reached 100 ° C and the rise again 9 - 14 % between temperature reached 100 - 200 ° C due to the water of small hole in the concrete disappearing increase concrete structure friction and aggregate reciprocal locking strength.

(2) Remarkable livable brand construction
Taking “China Green City”, “China Water City” as the fulcrum, start Nanning city brand.
The city has formed good habits of stressing social morality, professional ethics and family virtue
With the rapid expansion of Nanning City, infrastructure needs covering urban transport, water supply, electricity, energy and other needs expand exponentially, and the contradiction between demand and supply is gradually reflected.

The ingot was cast into a water-cooled copper mould with a size of 100 × 40 × 20 mm3 provided casting a cooling rate of about 15 K/s.
Specimens were prepared by mechanical grinding, polishing in colloidal silica based suspension, and anode oxidizing in water solution of 10 % (HF in H3BO4) in case of the analysis in polarized light.
The superplasticity characteristics were determined using uniaxial tensile tests on a Walter Bay 100N machine and a professional program service to control the traverse motion.

Readiness for and response to radioactive emergency incidents in emergency planning zones are addressed in professional publications by the International Atomic Energy Agency (IAEA) [7], [8].
Basic physical attributes of building materials can be divided into five basic groups: - Attributes related to fire safety:heat resistance, stability in fire, thermal expansion, thermal conductivity, accumulation capacity; - Attributes related to protection against mechanical stress: strength in compression, traction, slide, bend and torsion, elasticity and pliability, hardness; durability; wear and tear; - Attributes related to protection against water effects: absorption, humidity, diffusion, capillarity, water resistance, frost resistance; - Attributes related to protection against sound: air and step attenuation, speed of sound; - Attributes related to protection against permeability of dangerous substances: surface density, bulk density, compactness, porosity.

Before bioscouring treatment the samples were washed with hot water at 100 0C in the standardized AATCC Lander-Ömeter, model M228-AA from SDL Atlas Company, United States.
After the bioscouring treatment, the samples were washed with hot (70 0C) and cold water and dried at room temperature.
The central, rotatable second order compound program has the following mathematical expression presented by Eq. 2: Y = f(x,y) = b0 + b1x + b2y + b12xy + b11x2 + b22y2 (2) For the experimental data processing the Mathcad Professional and Excel software were used, resulting the regression equations [3],[4],[5].
